Latest Posts is not centre aligned

Hi, I've never had this issue before and have used GeneratePress a lot.

I've created a sidebar area in a container, and put in Latest Posts widget. Despite setting it all as being centre aligned, it's showing as on the right hand side of the container, despite Inspect showing everything being centred correctly.

It's as if there's padding on the left, but there isn't in the container view so I'm stuck?

Thanks
