Unknownw port conflict - literally unknown

Any suggestions on how to troubleshoot this error?

Unknown Port Conflict
An unknown port conflict has been detected in PJSIP. Please check and validate your PJSIP Ports to ensure they’re not overlapping

SIP is using 5060/5061 whereas PJSIP is using 5160/5161

In fact, PJSIP is disabled.

I’m thinking of completely stopping Asterisk from loading PJSIP modules.
