DFHH0003E from Health Checker after upgrading to CICS TS 5.4

Question

I just brought up my first CICS region , a CMAS, under CICS Transaction Server for z/OS (CICS TS) V5.4. Health Checker seems to be working okay as I see messages being sent to the z/OS Health Checker every 30 minutes. However, I also see message DFHH0003E. The message implies my default region userid has access to a TD Queue defined to the INTERNAL Reader or to the CECI transaction. However, I do not make use of the INTERNAL reader and I have confirmed the userid does not have access to the CECI transaction.

Here is the output of showing the error:
