Not sure why but you may edit them using catalog manager offline manager.
Txs... yes, I can edit them in offline mode... but it is kind of tedious (stop servers, etc) /
As far as I understand it should be possible to edit it via Answers > catalog... Maybe I am missing something.. any hint ?
Not sure exact reasons, but this can be fixed as said.
I dont think you are missing anything since its oob webcat folder... it also depends how Oracle extracted it
