Files not showing in repo list
### Describe the bug

I added a new Sketch file into an existing repo. Pushed it to our on-prem BitBucket instance, and everything is fine. I can make changes and push/pull without issue.

My co-worker had pulled the repo before I added the new file.  When they do a pull, the folders and content from the new file appear on her Mac (using Finder to look at the folder) but nothing shows in Kactus.

### Version & OS

We're both running Kactus Version 0.3.26. Mac OS Mojave 10.14.6
