Help with adding text field/auto filling previous entries from different devices

I use Adobe Pro DC on my laptop and iPad. My subscription allows me to use it on multiple devices. A while back I had my wife download and log in to it on her laptop for work so she could edit/export PDFs to excel/word/etc. 

I noticed today that when using it for fill&sign, that when I click the "add text" button, a new text box appears like normal...no issue there. What's odd is that if I type in the word "the" or any random word, a drop down appears showing ALL previous entries with that word in it, similar to how "autofill" works. Usually it would be helpful but it's not just showing MY previous entries. It's showing entries my wife has made as well. I'm aware this is probably because she's under my log in. My concern is that if she used the program to fill in client information that could be considered "confidential" that it will show up if I "add text" with the same word and that she may unknowingly be giving me access to client info from her office. Example. If I type in my area code, a list shows up to fill from showing all phone numbers she has entered with that information. She doesn't work in a position where this would be an issue necessarily but my question is.. if text shows up on that drop down list, does that mean it has definitely been entered by either me or her? Just looking for confirmation. I came across text I assume she entered and the subject of it is of great personal concern to me. There's no way i entered it and I just want to make sure before I bring it up to her. Thanks.
