Refreshing (either from the menu or by hitting F5) does not solve the issue.

When I go to the Log / History view, I can see the files (I thought previous times I did not, so this may not be consistent).

I attached three screenshots to illustrate.

(After taking the screenshots I tried to close and re-open SourceTree again, and this time the files DID get updated. See Bug4.png)
