Just downloaded Audition and there are random "recent" files I've never heard of.

I've had an Adobe subscription for ages, but just recently needed to download Audition. I went to "Open Recent" to continue working on a file, and noticed a handful of files in my recent that I've never heard of... included ones named "ummmm.sesx", "sounds.sesx", and "CASHMEOUTSIDE.sesx".

Obviously, when I tried to open them they couldn't be located. Is this a glitch? My first thought was that someone had gained access to my account, but my license is already active on my desktop and laptop (max activation) and I've never gotten kicked, or had any indication on my other apps' recent history that someone else has used my account.

I'm running Version 25.3.0.71 on MacOS Sequoia 15.6.
