Blog boxes set to 3 only shows 1

I have the blog boxes set up as it was in the “shop theme” with three boxes on the home page. Only one will show, I have tried and looked everywhere. the settings is on show 3, there are three posts to show set up. This started after I adjusted the dates.

However I can’t find anywhere there is a date limit set.
