Hi there, fantastic plugin first off and thank you! I ran into a conflict with Events Manager where the Events Manager content for a page was displaying where my Content Blocks were. Basically duplicating the content. I did post the issue in their forum but ended up solving the problem by modifying the query in your plugin. Here is what I did:
Now, I'm not sure where the problem lies, I just know that this modification fixed it. It's still querying like it was before but instead of using get_post() I'm using WP_Query() and passing in the appropriate variables just like you were.
Maybe you can shed some light on this or maybe this can help others out there running into the same problem where queries are duplicating. I hope so.
