 * I am constantly getting the “This block contains unexpected or invalid content.[
   Resolve] [Convert to HTML]” for core blocks because “Block Validation failed”
   in the console. I am not sure if this is because you are extending the core items
   with the added features but this is very disruptive for our clients. Is this 
   a known issue and is a fix coming soon?
 * index.js:2 Block validation: Block validation failed for `core/image` (Object).
 * Content generated by `save` function:
 * <figure class=”wp-block-image alignwide size-full has-animator”></figure>
 * Content retrieved from post body:

 * Hi [@styledev](https://wordpress.org/support/users/styledev/)
 * This is not a known bug but a first time. I wonder if another plugin inflicting
   the cause of a validation issue since I see there are a couple plugins installed
   on the site.
 * Also, I figure you’re using the development version of the Gutenberg plugin. 
   Kioken Blocks is tested working well for Gutenberg plugin up to 6.8 and not tested
   for 6.9 and 7.0 (which was released yesterday) yet.
 * I would suggest using the block editor in the WordPress core, not the development
   version of the block editor.
 * Thanks!

 * I revisited this issue but couldn’t reproduce but I still have a feeling it may
   be about the Gutenberg plugin.
 * Could you try turning off the Gutenberg plugin and use the block editor of the
   WordPress itself and see if it resolves the issue?
 * Thanks,

   this topic since I’ll assume it’s resolved.

 * [@sj_o](https://wordpress.org/support/users/sj_o/) I disabled the Gutenberg plugin
   and I am still getting the conflict blocks, further when I go to resolve there
   is no difference in the Diffs though it does highlight code the code is the same
   as the original. This is happening specifically with blocks that specify font
   changes. When I click resolve though, the font changes are not carried over to
   the resolved block. Maybe this has to do with the blocks being originally created
   with the Gutenberg plugin active.
 * I am assuming though that what ever is causing this issue with the Gutenberg 
   plugin you will need to resolve it by the time WordPress core upgrades the core
   version to the latest plugin version of Gutenberg…
