Styling issues using UAG blocks in Popup Maker’s popups

Hello,

I’d like to use UAG’s Section, Advanced Header etc blocks in a Popup Maker popup theme where Block editor content can be used, so I’d like to edit popup with Gutenberg,
but when using UAG blocks, it has styling issues.
(Popup theme used: “Content only…”, block editor support must be enabled at Settings/General)
PM support tested it thoroughly and they think the cause is on UAG’s side.
Standard Gutenberg blocks are styled properly in them, but not UAG’s ones.
Thank you
