Optional extended integration settings disappear on restart of SourceTree

NB: This is in version 3.38, but that version does not show up in the list of versions!

I set up credentials for Bitbucket Server so I can create pull requests. Everything works fine until I exit Sourcetree. When I restart Sourcetree, my remote account integration settings are lost and I can no longer create a pull request. Likewise for "View repository online".

I am using a "saved account". That is still present after a restart, but it is no longer assigned to the remote repo.

The behavior is very similar to SRCTREEWIN-8293, but this happens even when I am connected to the host repo network when SourceTree starts, so the root cause may be different.
