I'm using ublock Origin and have never seen any of those.
For those with ubO who still see them, cleaning the cache and updating the filters within ubO seems to help.

Basically disable all current ad blockers, including YouTube enhancer ad blocker, reset filters to default, make sure there's no cosmetic filters either. And it should work L.
I just used the picker, removed the elements, saved it, and haven't looked back.
I also did this with the stack overflow nag.
Gonna try the ublock reset as outlined above, failing that I'll test uMatrix to turn off / lobotomise specific scripts.
