Can you please explain why my menu formating keeps changing from norman to all bunched up together a lot smaller?

I haven't edited my website recently so maybe a recent update that you have done is effecting the menu or Elementor plugin.

As you can see from the attachments, it only looks normal when I've signed in.

Cloudways doesn't allow you to disable Varnish and it was your team that recommended Cloudways

I've doubled checked and it says it's already disabled
