Wordpress and broken links in SEO

So having problems with SEO and broken links. All my links that is in the menu is broken links. But seems to work. All links is linking to categories in the shop. Any ideas on how to solv this.

Can you please let us know your website and post some example links so we understand better what you mean? Thanks!

Site is meandmytee.com. When i do a seo check on the site or check for broken links all the links in the menu pointing to a spredshirt category is broken. But not the links below the menu. For example https://meandmytee.com/store/men?q=D1. So its something with Wordpress menu linking to spreadshirt.

no awnser?

Still having problems with all the links pointing to spredshop pages
