UAC dual screen issue W10

On windows 10, up to date. About half of the time that I start a program that requires UAC it will show up on my primary display, the other half on my secondary display. The problem is my secondary display is my TV and the UAC box deciding to pop up in when I’m streaming on the TV and doing stuff on my computer is a major pain, or when I’m gaming on my TV and someone else uses the computer and it happens. I’ve checked that my monitor is the primary display, switched displays and then changed them back to see if that would somehow fix it, obviously it didn’t, exhausted my googling powers trying to find a fix besides killing UAC entirely which I don’t want to do, I remember with W8 I didn’t have any issues like this. Any ideas/suggestions?
