Reusable blocks styling broken when inside Advanced columns

I’ve created a reusable block that includes your ‘icon list’ block as well as a 2-column ‘advanced columns’ block. It’s the entire white section called ‘Packages and prices’ on the page linked.

When I add it to a page not inside ‘advanced columns’, it renders perfectly. When I create an ‘advanced columns’ block (necessary for my use case, to give different background colors when necessary), and add this reusable block inside it, the styles set on the ‘icon list’ block are removed.

Specifically: icon size, and center-alignment.

Also, the 2-column ‘advanced columns’ block that I applied a border to, and column padding… is also ignored.

Please can you investigate ASAP?
