hey there! I am SO SORRY!
There seems to be an issue with the forums I was actually just on this forum yesterday on November 7th, which was after your second and third request, however, this thread was not even visible to me. I will post this to Automattic and see what the issue there is.
However, to answer your question – make sure that when you are in PauPress Options > Manage Fields you check the option for "Reports" – this will enable your custom fields for BOTH the search engine and your forms.
Again, apologies for not being able to respond to this sooner.
