Why are deleted documents saving to the "Home" folder in File Explorer? Can I stop this?

I've got a new laptop with Windows 11. When I open a Word document from LEAP, then edit & save it, a copy gets saved to my desktop in a folder called "Home", which is easily found in File Explorer. These saved documents are readily opened from the "Home" folder, even when LEAP is closed.

Can I stop these saves? These documents could potentially be the source of privacy, confidentiality & cyber security breaches. But one of the reasons I use LEAP in the first place is to store my files in a secure environment! Sort of defeats the purpose of using LEAP if the "secure" program is actively creating information insecurity problems.
