Fix service text output in bitrix work template

There is a ready-made installed template Aspro: Medical Center 2.0 and when you get to the service page there are nav-tabs with tabs: Description, Prices, Questions and Answers, but at some points when you click there is a failure in the output and the output is a crooked code that interferes with the elements and turns into a hodgepodge.
Heres one example: *link*

The second thing to fix is the wrong encoding: Example *link*

From the working material there are: the main site of the seller where the template is installed and the data of the problem is not noticed (suitable for comparing the code) and the newly installed template on the closed site from users (data from the admin panel will be provided).

The customer is required to specify the files where he changed the code and line numbers, in fact and the (new) code itself.
