relationship sort order not saving

[fullyloadedtech]

Setting sort order with ->multiple()->relationship(...) doesn't seem to save - is there some sort of requirement for the pivot table? The drag & drop sort works but after save/refresh the order is not saved.

I see that Filament uses ->orderable() for a sort column but getting "CuratorPicker::orderable does not exist" https://filamentphp.com/docs/2.x/forms/fields#ordering-items
