TeamCity keeps checking out main branch code instead of feture branch

Hi all,

I'm using teamcity to set up a custom build that will checkout the source code from preview/13* and versions/13*.

This is my configuration:

Default branch: refs/heads/main
Branch specification:
	+:refs/heads/(preview/13*)
Branch Filter:
	+:preview/*

When I manually trigger the build as the below screenshot:
 

Then I got this issue:

Seems that it still checks out the Default branch because in the Preview branch, I have moved my Dockerfile into apps/web/Dockerfile.

Thanks,
