Seems this is broken in Django 2.2.

Ticket 29917 discussed this (with mixed opinions) and although it is marked as fixed, the issue remains.

My observation shows that nothing is broken in actual functional code (actions do work and are not collected twice on inherited ModelAdmin classes). It's just that noisy warning that's trying to be too smart.

You can simply disable it by adding this to your settings:

SILENCED_SYSTEM_CHECKS = ['admin.E130']
