I am having a problem with BlockMag

I've tried the WordPress support forum - no luck. I've tried /WordPress - no luck. This is my problem: Whenever I upload a new post onto my 'Blog' page, all of the free text on my 'Home' page (below my website title and my pages links banner) completely disappears. As soon as I delete the blog post, the text on my 'Home' page all comes back. I have my home page set to 'static'. Does my issue make sense? Does anyone know how I can fix this? Please let me know if any more information is required. I am very new to this. My site is not yet live as I need to fix this issue first. I'd be very grateful if you can assist me!
