"Fixed at" field in "report info" is missing date, despite the issue having been fixed

I am browsing through a small product in our CodeChecker (v6.27.3) which has had issues found since 2020 that it was introduced. Frequent analyses have been running ever since.

For one specific report-hash, I see that

• it was first detected in 2020-11-12
• it shows "review status" as "confirmed bug", because someone had reviewed it and marked it as such back in 2022
• it was fixed shortly after with a patch
• it was last detected in 2022-03
  • this is not indicated somewhere, I have to scroll through hundreds of runs in the "found in" dropdown at the top right and find myself.
• clicking on "report info" I see that it is indeed a "confirmed bug" first detected at 2020 but the "fixed at" field is empty.

My questions:
Why is the "fixed at" field empty, even if it hasn't been seen in any runs since 2022?
Can the UI also display the "last detection date"?

Related: I see zero issues marked as "resolved" on any stored run all the years of CodeChecker history of this project.
There is something wrong definitely.

Shouldn't CodeChecker auto-detect non-existing report-hashes in a new run, and mark them as "resolved"?
