Metadata doesn't show up

they worked very well but when updated app on apple tv 4k, some metadata don’t show up.
I have to go to each movie and click edit and match metadata one by one.
already uninstalled and reinstalled again on apple tv.
is there any suggestion?

There’s a thread in the Metadata forum that may shed some light on what you’re seeing.

I already did as mentioned in that thread. However, in some movies, it remains as a white poster even though the metadata inside is correct.
the pics can be seen below.

There is a 6.4.1 update due out very soon that may fix this. I’d suggest waiting and seeing if this update cures the problem.
