Do not worry. It is said by physicists that if you think you understand quantum mechanics you don’t.
I think that’s probably because NOBODY really understands much, yet.
And every time we reach any sound ‘understanding’ of any little thing, there’s going to be another puzzle before us.
This is the inherent problem with the Great God Science, and especially with the politicization of science.
The notion that anything is ever ‘settled’ is nonsense; and it’s erroneous and insulting toward the values - and history - of science itself.
