Why are meta tags not displayed on the site when checking, although they are in the console?

Question

opencart

Good day. Meta tags are not displayed on the site when checking. When the page is viewed in the console, the tags are visible. When you feed a page to a site that checks meta tags (for example, page-speed.ru). He does not see meta tags there.
An example of the page https://audioceh.ru/mt-power-master-speaker-wire-a...
