Trouble with publication in blog section

Hi sirs.

I’ve a problem with this site: www.ristorantedonpepe.it

I send a screen shot to understand better that I mean, bottom this page

I’ve created a post, inside blog, using “page buolder. But in Home Page, under the picture compares all the “html code”. Why?
If I use normal editor it’s ok.
But I’d want use “page builder”. May be I was wrong some setting. I don’t know!!!

Can you help me, please?

Thanks a lot

Best regards
