When adding a remote repository in Sourcetree from a Bitbucket account the dropdown to select which workspace has a line for each workspace and you can select them but the lines are blank.

The same with the Light theme

I've tried reinstalling Sourcetree, including wiping user settings/config, to no avail.
These are the workspaces that I have on Bitbucket and are definitely the 2 things im choosing from in the dropdown.
