Devolutions Cloud browser plugin not working for some entries

Hi! We have (since a couple of weeks) problems with the browser plugin for logins. For some entries, we get an error "You don't have sufficient rights to perform this action". Other entries work fine. When I switch the source of the plugin to RDM, all entries work. The source for RDM (and Dev Cloud) is Devolutions Hub Business. The problem seem to have arisen after some entries were suddenly deprecated. I have converted these entries. I'm not sure if the problems are now with the converted entries or not. In Devolutions Cloud I cannot see any differences in the items. I am vault manager, so I have all the rights on all the entries. What can be the problem here?
