Wordfence Central Sorting Issues

We have some 40+ websites on our Wordfence Central dashboard. One of the features, though, doesn’t work as expected. That’s the sorting. I should be able to click on any one of the headings to sort it. True, something happens when I click on the headings, but the results are unexpected. For example, when I click on ‘Highest Severity’ I don’t expect a website with 0 issues to be at the top of the list. I would expect something with 4 or 5 issues at the top. When I click a second time on the same heading, I don’t get the reverse sort either. It’s just a jumble. The same is true if I click on ‘findings’. I would expect that sort to be relatively simple, going from 0 to some higher number. Nope. I do get lots of 0’s first, but then I get a 5 and then a 2 etc. What gives?
