The Database Tables Exclusion page appears illegible.
The ungly look of the Database Tables Exclusion page happens only on Chrome, Opera, Edge, and Avast browsers on my Windows 10 computer.
Firefox displays the page fine.
The problem seems to be the combination of "float: left;" and "display: inline-block;" for the ".table-container span.table-icon-container" elements. Firefox seems to recognize the problem and automatically rectifies it by disabling the "display: inline-block;" as it points out too.
Try changing the CSS of those elements into "display: inline-flex;"
