Signal of record type connected to input/output port of same record type reports a mismatch

Hi, great to see that you like our project!
Unfortunately, I cannot seem to reproduce your error.
Note that it's best if you provide a minimal reproducible example (ideally as code instead of screenshots) so that we can investigate the issue faster. The example that I used is the following:

library ieee;
use ieee.std_logic_1164.all;

package test is
    type record_PWMmod_3_train is record
        Pulse_Train_T_on : std_logic_vector(15 downto 0);
        Pulse_Train_Period : std_logic_vector(15 downto 0);
        Pulse_Train_Repetition : std_logic_vector(15 downto 0);
        Pulse_Train_BreakTime : std_logic_vector(15 downto 0);
    end record;

    type record_Package is array (19 downto 0) of record_PWMmod_3_train;

    type record_type_PWMmod3_package is record
        Train: record_Package;
        Pulse_Energy_To_High : std_logic;
        number_of_Train : std_logic_vector(15 downto 0);
        start_Package : std_logic;
        Pulse_Train_Active : std_logic_vector(19 downto 0);
    end record;
end package;

use work.test.all;

entity test_ent is
    port ( train : in record_type_PWMmod3_package );
end entity;

use work.test.all;

entity test_ent2 is
end entity test_ent2;

architecture rtl of test_ent2 is
    signal rec_PWMmod_3_Package : record_type_PWMmod3_package;
begin

    test_ent_inst: entity work.test_ent
     port map(
        train => rec_PWMmod_3_Package
    );
end architecture;

Is this similar to the setup that you are using? Does this example also cause the issue for you?

Hi. Thank you for your rapid response. Your example runs fine on my side. I've digged deeper into this problem. Turned out it is not really an issue from your side. I was handed an old project in which someone clearly did not pay attention to proper library management. I managed to reproduce the issue in this minimal example:
github_issue.zip

As you can see I've duplicated declaration of test_record_pkg and test_module both in work library and global library (see vhdl_ls.toml).

Once I will try to instantiate test_module from work library it is throwing the mismatch error (even though the navigation of the declaration points to the same record type)

Once I will do it properly, and throw away work library declaration from .toml and refer to test_module as a part of global library it is working completly fine.

Strangely it is not reporting the "record already declared" issue which is present when you duplicate the declaration in two separate libraries.

So one issue with the vhdl_ls.toml of yours is that you have called one library work. This is not a legal library name in VHDL and was disallowed starting from version 0.78.0. This is because the work library in VHDL has a special meaning as it points to whatever the current library is.
There is an error being shown in VS Code, but I'm afraid that error is not visible very well. It's just a message that pops up. All other files are being opened in "non-project" mode, i.e., they are analysed and parsed but the vhdl_ls.toml file is ignored. But I think that's where the weird behaviour that you see comes from. Maybe the work library topic should be handled in another way since many people seem to have this problem.
