Answer 1

You should see this issue if you've upgraded to magento 2.3.5-p2. This issue comes up when you have more than one page builder elements on the same page. Mostly causes issue when you have a custom page builder element on page for your custom attribute.

To fix this issue, in your uiComponent add the following item nodes under wysiwyg config.

<item name="is_pagebuilder_enabled" xsi:type="boolean">true</item>
<item name="pagebuilder_button" xsi:type="boolean">true</item>

You can find full example on github issue page https://github.com/mirasvit/module-blog/issues/162

Note: This has been fixed in Magento 2.3.6 https://devdocs.magento.com/page-builder/docs/release-notes.html#133-for-magento-commerce-236
