Don’t know how is the progress in this, but I managed to find an easy workaround to make the sorting buttons of a specific table work again:
Just change the number of rows displayed per page:
after you change it, the sorting buttons start working again and you can change the number of rows back to your preferred option.
Don’t know if this helps find / fix the problem, but at least can help those that are experiencing this for now.
(Another info: I always use 100 rows per page. Don’t know if this could be the original cause, but…)
