Sourcetree not restoring tab names

In SourceTree 4.2.4 - I'm finding that the tabs are showing the full file path - instead of the repo name when the app is reloaded.

I've attached the screenshot. The top screen is proper - and shows how the tabs are named when I load the repos via the repository browser directly.

If I exit and then re-launch sourcetree - the tabs look like the bottom window - with full paths instead of the names...

In fact - if I double click on a repo from the browser - it will load it a second time!

[Update - on a hunch I deleted the repo from my list and then re-added it. That seems to work - so it's a suitable work-around for folks.]
