Dev Build 26220.6982 trying to force install itself on PC's

OK, does anyone else have an issue with WU trying to install the DEV build on their PC's? This has happened to me twice now in the last week, just now on the current beta build 26120.6982 and a few days ago on my girlfriend's laptop which isn't even on the insider problem and was on the latest public build. It suddenly shows up in WU out of the blue and I have to pause updates. To finally stop it on my girlfriends laptop I had to use a YouTube video and jump through a bunch of hoops switching back in forth from MS account to local account and changing all kind of account stuff to get that PC back to showing public builds again. Now the same issue on my old Beta PC and it's locked on the DEV build again and can't be changed. What the heck is going on with this update showing out of the blue. I can't select any insider settings or unenroll.
