I saw the page. The issue is not related to UFW plugin.
You have to check with the “coblocks” plugin team.
The block is not made visible in chinees language whereas the same block is visible for english language.
For english lang:
wp-block-media-text alignwide has-media-on-the-right is-stacked-on-mobile
for chinese lang:
wp-block-media-text alignwide has-media-on-the-right is-stacked-on-mobile coblocks-animate slideInRight
These are the classes set on the block. coblocks-animate is still present and not executed hence it is not displayed.
