Compatibility issues Nectar Blocks and Woodmart 8/Gutenberg Builder

Hi,
I received this reply from the team behind Nectarblocks Website Builder. I want to use some of their blocks occasionally with Woodmart/Gutenberg but when activated it stuffs up the Woodmart layout when editing in the backend. Can this be fixed/patched/sorted?

Please see below: From Nectar Blocks Support:
Hey Kevin,
When a third-party theme is active, Nectarblocks uses the default WordPress variable –wp–style–global–content-size to determine the content width. I assume that Woodmart is not setting this variable to align with their theme’s container sizing. However, they should set it to ensure the best compatibility with other Gutenberg plugins, as this wouldn’t be something we could add from our side.
Kind regards, Nectar Block Support.
