sean No, no errors. I should mention I'm using Firefox 82.0.2, in case that's relevant.
I can reproduce this easily. On my dashboard:
- Go to "Email Addresses".
- Filter using "maj". There should be 13 entries shown.
- Click on the "Source" column heading to sort on that column. Note the lack of expected ordering. Click on the heading again to reverse the sort - it still doesn't sort as expected. When the sort is ascending, the initial letters of the first entries are c, t, w, y, y, c, e. When the sort is descending, the initial letters are y, y, w, t, c, u, s.
