I use UserSpice on the pages with different reports and I met with the issue with the sort signs in headers in dataTables.
The solution - I change the datatables.css with the new version from https://datatables.net/download/ and created my version of header.php where in line 165 changed the jquery version to 3.3.1
It solved all my problem.
