Templates selection are broken

Hi :slight_smile:

I don't know exactly when the problem appeared but it was just a few days ago maximum.
As you can see here:

The layout is broken.
Before you hade just the thumbs so about 6 in a row, so it was nice :slight_smile:

What happened? Is it related to the latest update of New Blog Templates?
How can I fix that?

Thanks!
