No title tag or meta description on my URLS

[seoraketten]

Hey, I have the website https://tech24.dk/ and my last site audit in Ahreffs, told me that I had plenty of URLs that doesn't have a title tag or meta description. I can see in my dashboard --> collections, that it has generated a title text and short description (SEO meta description) but when I go check my HTML there is no title tag showing? 

Can someone please help me? It says the problem is currently showing on my 4000+ sites on my webshop. 

Can you somehow code something that will make the title tag appear? 

best regards, Joakim
