I’m finding some of the Smart crates from Serato show up in Rekordbox as ordinary crates.
And some Smart crates show up as they should, Intelligent Playlists.
I’m attempting to change sorts of parameters but nothing has worked.
Can someone please help 
Some rules are slightly different or not supported at all in RB so smart crates with those rules can’t become intelligent playlists in RB, they are turned into normal playlists automatically.
Oh ok yeah I thought maybe that was the case. Is there a guide on which rules do work?
It’s not documented but most rules should work, just the date and filename rules are exceptions
