Suggestion for finding observations with missing or incorrect location or date:

In my case, it helps to find observations that need a fix (for instance this observation whose location I have just fixed, and I fixed the DQA flag for inaccurate location).
But in your case @graysquirrel nothing to fix in the results, almost only observations marked as “it’s as good as it can be” in the results.
