Album type is not working in Smart Album Playlists

Issue description:

I’m trying to create a smart playlist of Soundtracks, but when applying any rule based on album type no albums are returned.
I’m pretty new to Symfonium but I’m sure I tested a similar scenario with the previous version and it worked, so I assume this is a regression in 11.4.0.
“To support clickable album types, the values are now normalized before storing them in the database. You may need to update your smart filters!”

Albums are correctly grouped by album type in the artist view, and all the types that are available in my collection are correctly presented when building the rule in the smart playlist.

The “contains” clause works, is that the expected behaviour?

Was about to post this issue myself, when filtering by album type on song/album list.

‘Contains’ filter works, but not ‘is’, even when selecting from the pre-listed values. Also, when filtering on the songs list, there is no option for ‘contains’, only ‘is’ or ‘is not’.

I’ve also just noticed that DJ-Mix is being translated to djmix when rule building in Smart Playlist creation. It would be nice if it was aligned to how it’s used on the Album page i.e. DJ-mix.
