[2022] Custom Blocks are not getting embedded to the track when editing campaign tracks

So I am working on an altered version of the campaign. When I'm trying to use custom blocks (for example flink ice blocks) they won't get embedded into the track meaning when I wanna play the track after validating I get this error notification that the custom blocks are missing. This is a newer problem cause it recently worked out fine.
Also it only happens when editing campaign tracks. When I build a new track or edit an other track it works out fine and I get the "note: x amount of blocks will be embedded to the map" notification while saving the validated track. While on the edited campaign track I don't get any notification on the custom blocks.
I hope this problem will get fixed soon.
