When a commit is selected, I no longer see the file list for the changed files in the commit (expected on the left side of the lower panel below the commit information). Attached are two screenshots of the same repository, selecting the same commit, but changing the display options for the files changes which one is selected, therefore what diff is seen to the right.

I thought maybe it's hidden and can be dragged up from the bottom, but that only shows the Command History.

This is happening in all my repositories.

This makes SourceTree unusable as I cannot see the full content of previous commits.
