Table add-on on mobile - BUGs

[joomleb]

Hi,
PHP 7.4.15 + DB 5.5.5-10.3.24-MariaDB-cll-lve + Joomla 3.9.25 + SPPB 3.7.9

• Table add-on > Turn Off Responsive: Yes
• by using Headings add-on into a Table row add-on, when I add the Font Size for mobile

A - on Backend the Table is shown as with "Turn Off Responsive: No" - here a video
B - the Heading Icon / Text on Mobile screen are not shown inline, but on two lines... it seems like a "small max width" for the the first column table has been added... - here an image - here the live page affected

Please, Can you fix them ?
I attach also the Table page for testing
