Navigation Block looks wierd after updating website

Hello, I am new to WordPress and Gutenberg, I like Gutenberg very much and having fun learing how it works.

So the problem is that the Navigation Block seems to end up looking bad after updating my page. In the Gutenberg builder looks fine, the problem happens only in the live version of the website:

The only plugins I am using are:

File Manager and Editor Plus,

I deactivated both and the problem still persists.

Here is how it looks:

I’m a bit lost.
Any help would be appreciated

Thank you.
