Saving documents in iCloud Drive from Microsoft Products

I have been saving all of my MS Office documents (Word, Powerpoint, Excel, etc. - Version 15.25 - Office 365 for Mac) in iCloud for several months now. I recently did an update, and it no longer shows in places I can save from within their program. (This also include Adobe Acrobat Reader) I can still see iCloud in Finder. Does anyone have any suggestions?
