My only guess is, you have your Custom Trust List and you currently have excluded some people who trust Dabs. That's why you've been seeing less Trust Score of Dabs.
Nothing more. For I also checked Dabs' trust score using my alt with a default settings. I also get what asu's have seen.

Sooner or Later I'll have you make an edit on that list and include my name on DT1 😂
