Issue with editing my Home page

I have a problem on my Home page. Almost all my modules moved to the left … and are not centered anymore.
I have created the home page mostly with 2 rows. Now there are still 2 rows but a big space to the right (and I don’t think it comes from the margins).
Anyone can help me please ? I’m not an expert …

Many thanks in advance :slight_smile:
