That is the server behavior that can't be modified because of the 'no properties' error referenced above. When I try to modify it, I get the error.
Also noticed the WADA Search server behavior looks like 'WADA Search (Unknown). Not sure if this is related, but tried opening and closing to reset it anyway, but no difference. Also tried selecting the 'Recordset (prodsizeselectlist)' inside the panel, but it deleted the existing setup. Recreated the setup, but made no difference either.
