Why did Google Analyitcs stop tracking ecommerce companies correctly?

Question

Google Analytics

Hello!
I ran into this problem in GA:
Previously, the company report looked like this:

It still looks like this, if you look at old reports.
In new reports, the same tab looks like this

: the income column is always zero.
If you enter e-commerce, it says that users made purchases after switching from the payment site (sci.interkassa.com):

Previously, the same old man looked like this:

The site works according to the system: A person accesses a link with UTMs => Selects a product => Goes to the payment site sci.interkassa.com => Returns to the site, where he is greeted by a successful purchase page and the script sends transaction data to GA.
The data sending script looks something like this, but it has never changed at all:

$item= "
  ga('ecommerce:addItem', {
  id: '".$id."',
  name: '".$item_name."',
  category: '".$item_cat."',
  price: '".$item_price."',,
  quantity: '".$item_count."'
});";
ga('require', 'ecommerce', 'ecommerce.js');
ga('ecommerce:addTransaction', {
  'id': '<?php echo $id ?>',
  'affiliation': 'ru.csgosticker.com',
  'revenue': <?php echo $price ?>,
  'shipping': 0,
  'tax': 0
});
<?php echo $item ?>
ga('ecommerce:send');
ga('ecommerce:clear');

The strangest thing is that nothing has changed, as far as I remember. Only the site switched from HTTP to HTTPS, but in GA I immediately changed the address.
With what it can be connected and in what direction to dig?
Thanks in advance!
