Programs - Single event without registration

Hello everyone
I'm working on a form for a program as single event without registration and I ran into a couple of problems.
- Even if the org. unit I'm woking on is already selected, the programs are not listed. I have to click a couple of times on the org. unit beforeI can see the list of available programs.
- The program started as a single event "with" registration and later on I changed the configuration as single event without registration, then the form stopped working. The form doesn't render after selecting the report date. I noticed the same happens with the Sierra Leone Demo (Inpatient morbidity and mortality), I was wondering if this happens because it started as an event with registration but I'm guessing this is not the case for the Demo.

Any ideas on how to fix this?
