I'd expect sorting from high occurrence to low number of occurences, the order that I'm getting back is pretty random...
ok this does look good on my end too, I probably confused the linenumbers for the occurences count, you can close this one.
We use this regularly and don't see this problem. The image you provided doesn't really illustrate the issue (I'd need to see at least one other crash below the first one that has more occurrences than the one selected in the current image).
