Why flex tablet is not working in columns but the others are...?

Hi all.
This page has a small column that is behaving the same way as my column with content.
On all mobile/tablet/portrait I want the 4 columns to stack so…
flex vertical
but in tablet the columns resize to small after setting flex vertical and they never reach edge to edge like the others.

here’s what I’m talking about:

Feedback appreciated…cheers

Using text columns to create a page layout is not recommended, use standard div elements and combination of CSS grid and/or Flex Box.
