How to replace a link to an image in bitrix?

Question

PHP

Hello.
The unfortunate developer-studio handed over the site to us on Bitrix ...
There is the following problem, the product is unloaded through an xml file, it contains a link to an image like site.ru/img/img.jpg
after uploading, they automatically substitute the protocol somewhere for links and it turns out http:// site.ru/img/img.jpg
if I change the address in the upload, to absolutely any, let's say I specify the link in the upload like this: https:// site.ru/img/img.jpg
then I get a link like:
http:// https:// site.ru/img/img.jpg
(spaces added to make links not clickable)
Where do they set it up? How can I find these substitutions in Bitrix? And where do such developers usually hide their developments? And yet, the link to the picture is stored in the database, in which table is it stored? I would like to see at what stage this substitution occurs.
ps Bitrix version 16.0.9 is not updated due to the fact that a bunch of errors occur during updates, and you have to constantly roll back to the current copy.
pss in Bitrix I don’t understand anything at all, a dark forest for me.
