Retrieve list max 30 roles when bind LDAP group name and role splunk

[aagro]

After the upgrade of Splunk core to release 9.4.0,  if I want to bind LDAP group name to role inside splunk (I have about 200 role), splunk show me only 30 role.
I tried to bypass this bug/issue setting it via conf file and then restarting the splunk service but this is boring.

Do you encountered this issue? How to resolve that?  

NOTE:

Environment Search Head Cluster

Splunk Enterprise rel. 9.4.0

Does anybody have an idea? 

Thank You
