Fields shown in selected Task Template field are different depending on user role

When selecting Task Template under Event Management, the fields shown in the Template field are different depending on the user role.

1. Log in as a user with the evt_mgmt_admin role.

2. Go to Event Management > Task Template, and click New.

3. Make sure the Incident table is selected.

4. Examine the drop-down options in the template.

   Note that the list for evt_admin contain only part of the fields of the incident.

This is operating as designed. Incident ACLs are defined out of the box to prevent templates for all fields except the allow-list.

Look at 
/sys_security_acl_list.do?sysparm_query=nameLIKEincident%5Eoperation%3De5a2b9c50a0a0bc5005dd4a3096ac37b 

The ACL name incident.* excludes all fields from the drop-down Template field, while the other ACLs listed include each individual field into the drop-down list. You can change this ACL to fit your needs.
