Acrobat is not saving the text I add to documents

I have been using acrobat to fill out and sign files I input form my OneDrive. I have not had any issues until not. I can open a file in acrobat from OneDrive,  but if I leave the page on Acrobat, all the information I input in the document deletes. This happens even if I leave the document and go back after only a few seconds. Sometimes I have to pause what I'm doing on one document and work on another; the one I pause on will be completely blank when I open it back up. Even if I stay on the document the whole time and then save it back to my OneDrive, all the information I put down deletes. I usually use this everyday for work, so please let me know if there is a solution as soon as possible.
