PHP Settings button is available while no PHP handlers installed on a server and proper settings in service plan applied. This results in an error about missing handler:
PLESK_ERROR: Domain "example.com": the PHP handler "fastcgi-5.6" is not registered
Resources and permissions for the subscription cannot be customized with the same error as above.
This is Plesk bug #PPPM-6125 which was fixed in Plesk Onyx 17.8 and Plesk Onyx 17.5.
Perform an upgrade to Plesk Onyx 17.5 or Plesk Onyx 17.8.
