Sorting Movies from release date not working for some files

Hi,

Some movies scanned are properly scanned, they show the right title, year, and cover but when i sort with release date they show up after the oldest movie i have, like 1924.

So they never appear in the right order, my fix is individually identifying them, and after that, they appear sorted correctly by release date, but every time i make a rescan of library they get wrongly sorted again.

Identifying manually over 20 movies every time i make a rescan is tedious.

This behavior happens even if i don’t update the movie file and previously scanned and identified movie.

How can i fix this for not doing manual operations over and over?
