Your description is a bit confusing. Can you describe a step-by-step guide to reproduce your problem?

Put the source connected to east side
Mark north face with fluid
put the Destiny connected to north face for output

is not working, nothing happends

now , Mark west face with fluid and the fluid begins to pass.

So you need to mark two sides (the nort side , and then west side) to work
Seems the opossite side of the source must to be marked.
