Timeline always switching when I set Timecode

I had this issue years ago, it went away for some reason and now its back. Can’t remember if I did anything to solve it. I have my timeline set to bars and beats, but when I set a timecode in “Set Timecode at Cursor”, my timeline switches to timecode, then i have to set it back, which I do for every project i work on. Anyone know how to keep it from switching?
