The Other filter seems to be breaking the content browser when enabling and disabling the selected filter. It seems to be happening to almost every filter in the other category, but not with other filters.
Work around Click in to another folder and click back into the content folder to populate what is actually in the folder.
This happens in 4.13 as well therefore not a regression.
Result: The content browser is populated with every asset in the project
Expected: The content browser appears the way it did before the use of the filter (only the starter content folder can be seen)
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-37717 in the post.
