Why is the Favicon not showing up on the homepage and category pages?

Question

opencart

ocStore Version 1.5.5.1.2
Good day to all! The fact is that favicon is displayed on all pages of the site, except for the main page and in categories, everything works on other pages, what could be the problem?
You can see it here.
I thought the problem is that the favicon is not displayed on these pages, but after looking at the page code, I see that it is displayed in the same way as on other pages

<link href="https://**.ru/image/data/суши/log2.png" rel="icon" />

what could be wrong?
