Since the last update there is a strange font for the row selection button in the frontend of a table. Maybe it is a google font despite google font is disabled.
Please can you check this and correct the font (standard font) as it was before.

Hi, thank you for your message.
This page is intended for feature suggestions, so the best way to resolve this issue would be to contact our official support team directly. They’ll be able to investigate the exact cause and help you fix it.
The issue might be related to your theme, active wpDataTables skin, or Google Fonts settings (even if they are disabled, the theme might be loading them).
We appreciate your time and understanding!
