Game updates broke my buildings

the inventory on my building was being added from event editor… and after the last few updates (not sure which one broke because I was a few updates behind) the items that are created from events just vanish from the shops on server restart. I know before it was an issue of them adding multiple so I manually removed to replace but now I need these to stay and something changed to where they get removed by default? How can I make the items stay after being created through an event?
