Plugin breaks TagDiv composer

TagDiv theme support indicates that the plugin breaks their TagDiv error. Here is their response:

Your tagdiv composer works perfectly fine for a brand new page so there is something on your homepage affecting the proper functionality of the composer. It appears to be this shortcode https://www.screencast.com/t/r3QsESrBt2rd
If I remove the shortcode, the page works properly again,

Can you please assist?

Thanks.
