mismatch in the total occurences between the cleartext and encrypted versions

I'm getting a mismatch in the total occurences between the cleartext and encrypted versions.
I'm using openFHE v1.0.1 on Windows 10 with MINGW64.

Output for strsearch_enc_1.cpp:

Read 1666846 characters
Limiting search to 32 characters starting at offset 16

Step 3.1 - Encrypt text
Given ringsize = 65536
and text size = 1666846
We can store approximately 26 batches in the CT

increasing batch size to 27
increasing batch size to 28
