PLEASE HELP–only certain emails send

When I create a post using a form tool that I’ve used for a couple of years my notification emails are sent as expected. When I manually create a post using the same Post Notification the result is no email and the notification is not listed in Reports. Upon inspection of the manually created post the block type is Classic Paragraph. The form-created block type is Classic. That is the only difference I can see.

I’m still new to WP 5 and don’t understand the block types very well. I tried manually creating the post with a block type of just Classic but that didn’t seem to work. Maybe I’m not doing it right.

Can someone explain if the different block type is the cause for the problem and walk me through the steps of what to do? If there is a block type dependency in Email Subscribers is that a bug or is it there for a reason?

I am using WordPress 5.0.3 and version 3.5.18 of the plugin.

Thanks,
Steve
