optimized version

first of all I’m sorry to ask this again, since I know i have seen this discussion some time back but can’t find it any more.
the situation I have is that, all my movies are setup to get optimized as soon as they get added, so far all is working.
however if I replace a movie with a better quality the old optimized versions are getting deleted, which is correct, but no new versions are getting created.
in th optimized version settings the movie is listed as “deleted” and I need to start the optimized process manually.
currently I have to check from timt to time if anything needs to get manually optimized, which is, if you have a long list of movies, quite timeconsuming.

is there currently any way to fix that?

thanks a lot in advance for all suggestions/help
