Simplify template: 2 bugs

Hello, I use Simplify template for my blogger blog.
I noticed two bugs:

  1. in the mobile version, the “cover” image doesn’t resize, so it can be seen only a detail of it.
    (see attached image: the main image and its “cover” version)

  2. in my home page i can see only 6 posts (the main post plus other 5, leaving a blank space on the bottom right):
    I tried to change this number in the “posts per page” widget, but it has no effect on the template.

Can you help me, please?

Sorry, the firs t image didn’t load.

Can anyone help me?
