How to display the correct meta title of the product in Bitrix?

Question

1C-Bitrix

Good day, there is a product (infoblock element) that is in three different categories, these three categories have different SEO title settings for elements, when you go to the product in different categories in the front, the same SEO title of the element from the category is pulled which is less than ID. Although, for each category, the title of the element from the settings should be dragged.
I take it out this way or that way
<title><? $APPLICATION->ShowTitle() ?></title>

<title><?= $APPLICATION->ShowProperty("title"); ?></title>

I don't think this is the issue.

Where to dig? Who faced? SEO-shnik heats the soldering iron.

Answer 1

What component are you using to display product information?
Suppose there are 2 options:
1. News in detail, the news.detail component which has the "Set browser window title" parameter (If this option is checked, the browser window title will be set according to the specified META TITLE SEO template (see the "SEO" tab in the info block ) or from a property.).
2. Catalog (complex component), catalog which has similar parameters "Set page title" etc.
Do you have them enabled?
