There does seem to be a fault here. What I can’t say (I’m not an employee of AIPRM, and don’t have access to the code) is whether the fault in in the software itself, possibly a bug introduced when the ability for cloning was added, or whether it is a fault in the instructions and expectations, but there’s enough people reporting an issue (lots more in Can't save/have my own prompt ) that I feel pretty sure there is a fault.
I have flagged this for staff attention by @aiprm-christophc , @aiprm-tiborb , @aiprm-mariang or @aiprm-mikek so please be patient while they catch up and investigate things.
