From version 3.1.2 to 3.1.3, the class uswds_grid is removed from the upcast for uswds_grid in editing.js. This is causing other embedded content elements that are wrapped in <div> tags to be upcast as grid.
Add a non-grid embedded content element (for instance, uswds accordion). In the source view, add a <div> tag wrapping the embedded content piece. <div><embedded-content data-plugin-config="{"process_items":[{"heading":"test","body":{"value":"\u003Cp\u003Etest\u003C\/p\u003E","format":"full_html"},"remove_item":"Remove item"}],"add_item":"Add item"}" data-plugin-id="uswds_process_list" data-button-id="uswds_process_list"> </embedded-content></div> When switching back to the non-source view, the content will disappear and the html changes to
<div class="undefined ck-widget" contenteditable="false">
</div>Add back the classes piece to the upcast for uswds_grid present in 3.1.2, the issue resolves.

I'm attaching a patch, I can't seem to push to the issue branch. I'll keep trying.
Would say keep using the patch but most likely I’ll have to start another branch and redo the grid plugin again. It’s really just a fork with tweaks but those tweaks seem to have issues
