Empty error messages

When Im trying save script after recording actions in Katalon Recorder im getting an empty error :

I think it has something to do with objects i capture during the test, many of them are duplication of objects i have used before, not sure what to do about it tho.

I also noticed that when I tried to open some of the Objects that i recently recorded have duplicated attributes and it is causing an error, I beilieve those empty errors are related to this

I also had this issue. The workaround was to create a new folder in the Object Repository.
