I wasn’t trying to imply that you didn’t know how collections work.
Your OP was not clear in the steps you were taking which made it seem like you were adding to the collection and also trying to use a smart collection to add the movie/create a collection. Your second post is much clearer and, imho, should have been how your OP was.
The only reason I posted what I did was because it wasn’t clear and if you did have a misunderstanding of adding collections, I figured I’d try and help and make sure you understood how it is done.
Friendly advice when asking for help (I work in IT and the support desk is still a part of my job), is to clearly outline the issue you are having and the steps you took that created the issue (if you are able to do so). Again, your second post would have been a much better OP as it outlines why you were using the smart collection after you encountered the issue.
Like it or not, when getting support, especially in a forum setting like this, there is a very good chance that whoever responds starts at the simplest level with initial responses (in my case clarifying what your issue was and confirming you understood how to create a collection). This isn’t done to insult your intelligence, it’s because, unless you’ve worked with someone before, you don’t know their level and even then I have had instances where working with someone that has the knowledge just forgot something simple.
Again, none of what I am saying is being said with any attitude or to insult your intelligence, it just comes from years of getting poor initial support requests and having to respond to get more information instead of being able to just start troubleshooting right away.
All that said, have you thought about trying to downgrade to the previous version to see if you can undo what the bug prevents and also see if it happens with a previous version? Had you created any recent collections prior to upgrading or had it been a while and you might have done an upgrade or 2 since your last collection was added?
I added movies to 2 different collections I had (actually the same collections you mentioned just with different collection names) prior to upgrading to the version you are on and everything worked correctly.
One last thing, you gave the player version but what platform is that? Also have you tried different player platforms to see if it’s server related or player related?
If nobody else responds by tomorrow, I’ll try and upgrade my test server to 1.25.0.5220 and create some collections and see if I can replicate (though I’m on Linux servers running Docker containers, so as long as it isn’t platform specific I should be able to reproduce). Since you only tested those 2 collections, do you think it has anything to do with the number of items in the collection? We know your Marvel collection should have 26 movies based on what you wrote, Bond should be about the same depending on which movies you include.
