Unable to Change/Delete objects and Object Folders

When trying to Change/Delete an object nothing occurs and the object remains.
I am only able to change or delete it by going on the actual folders and delete it there, followed by deleting it from the katalon app.
Regarding the folder its even more complicated i change the name of one but despite apearing ok on the actual folder location when i open katalon the previous name appears and i have to change it to the current again so that the objects appear.
The same issue doesn’t occur in other projects even ones created previously.
