What Operating System are you using (both controller, and any agents involved in the problem)?

Both Linux systems

Reproduction steps

1. Start Branch Indexing
2. Check Log

Expected Results

Branches already discovered and maybe even build are not detected as 'changed'

Actual Results

All branches in our system are detected as changed:
