As Joel said: check the logs. Things generally do not happen without being logged.
Is that prompt new or a migrated content? Do you see "2019" in the XML of the prompt?
By the way: you know that 22.214.171.124.0 isn't supported anymore for some time and it's also the most bugged of 12c being the very first release?
The XML you get it from Catalog Manager.
As it's a migrated object it can also have pieces in the XML which aren't in the GUI anymore (because of the change of versions).
If you delete that prompt entry and create it again do you still have the issue?
Nothing I can see in the XML. We recreated the Prompt from scratch and still have the same issue. We are going to pull the RPD down from Prod to DEV.
