I was going to report this exact same thing.

• The problem only happens with the plugin (Version 10.7.2). The core version (5.7.2) works fine
• I was able to reproduce this issue both with Twenty Twenty and Twenty Twenty-One.
• This is affecting the Columns, Image and Pullquote bocks but NOT the Gallery Block.

With the plugin active (alignment is set to "full" but the block shows as "centered") :

The problem goes away as soon as we deactivate the plugin:

@nosolosw hi! Could this be related to global styles changes?

I believe this is the same issue as #32274 We're preparing a fix for that at #32454

Going to close this one and suggest people follow #32274 instead.
