For example, I have ~Lauda in my trust list, and extension did not show DT2 badge on his/her profile. After removing "~Lauda" from my trust list, now I can see DT badge regularly.
It can't possibly be related to your trust list. The extension doesn't know who you are and whom you trust/distrust. If you notice this happening again please check if "Show DefaultTrust position" is turned on in extension settings and if it is - let me know which browser you're using so that we could debug this further.
Is the same here, and I don't distrust Lauda. I have the DT settings ON, and there are not issues with other DT members, at least I haven't notice yet. (don't get confused, I've disabled the avatars
Interesting, she is on my DT2. Here's a rating >
