I think I see the issue.
Working column
<div class=”wp-block-column has-text-color has-background has-link-color wp-elements-d56ee3cbeeeec3455d5d553688e094c9 is-layout-flow wp-block-column-is-layout-flow” style=”color:#000000;background-color:#d1d1e1;padding-top:2em;padding-right:2em;padding-bottom:2em;padding-left:2em”>
Non-working column
<div class=”wp-block-column has-yellow-background-color has-text-color has-background has-link-color wp-elements-8381345f4180d39b5b8879fe5b04898a is-layout-flow wp-block-column-is-layout-flow” style=”color:#000000;padding-top:2em;padding-right:2em;padding-bottom:2em;padding-left:2em”>
Non-working column doesn’t get the same settings as working column. background color has been assigned differently. In working column, background color is assign in “style” section. Non-working column doesn’t have background setting in “style” section
