Keyword cuts when drag/drop to side bar?[ADDITIONAL INFO]

I am in 5e: Keywords and I attempted to place keywords into the H U D (which was blank when I opened it) and it seemed to work very nicely to highlight and drag/drop a keyword into the H U D, however, when I tried to highlight a keyword to be dragged and dropped into then Keywords list on the Inspector it created the keyword, but removed the highlighted text from the document.

The “cut text” only happened for moving to the keywords area on the Inspector, not the H U D.

Sorry, but I can’t duplicate this. Can you please enumerate a lot more on the exact steps leading up to this bug?
