Actions on RelationManager not showing even after disabling policies

I've commented the policy for

Series

model in

AuthServiceProvider

AuthServiceProvider

and disabled the policy checking on the

SeriesRelationManager

but still I cannot see the

create

edit

and

delete

options in the table. I've cleared the application cache and re-installed the

vendor

to prevent cache issues but still no luck.

I've attached the table picture and my

code in screenshots for better understanding. Any help would be much appreciated.
