Configuration page totally blank

Hello to everyone, I've just downloaded and installed component on Joomla 3.7.
When I try to go on
Components -> Helpdesk Pro -> Configuration
I receive a totally empty page.
The other options like Categories, Tickets, ... work properly.
Can you please help me?
Thanks in advance
