Hi @asmecher,
I got some help and managed to get new buid of the js code and added a line of code in the file controllers/list/submissions/CatalogSubmissionsListHandler.inc.php
but it doesn’t work 
I cleaned the template cashes, just in case and it doesn’t help. Tried with incognito mode also. The DB table ‘new_releases’ still contains wrong context (assoc_id).
Any idea what can be wrong?
Best regards, Primož
