Odd "double information" bug in Details pane.

I’m having an odd issue, and I’m pretty sure it’s a bug rather than a feature. Many times my input fields seem to be doubled in the UE4 interface, across the entire application. Happens in the particle editor as much as it does in the material editor, etc. Can someone tell me if I’ve mistakenly turned on a toggle somewhere, or is my UE borked?

Attached image shows the problem - the entire bottom half is redundant, doubled information.
