Why doesn't the mail template change?

Question

1C-Bitrix

There is a feedback component. The task is to change the mail template for this component call.
The essence of the problem.
When changing the EVENT_MESSAGE_ID parameter, the component parameters always remain like this:

Although when called, there is a completely different value:

In component.php I found the following code:

if($arParams["EVENT_NAME"] == '') {
  $arParams["EVENT_NAME"] = "FEEDBACK_FORM";
}

However, adding the EVENT_NAME parameter with the value of the template I need to the component call parameters does not change anything:

The mail template and the event exist.

The cache was completely cleared.
What could be the problem? Someone faced such a problem?
Thanks in advance!

If you asked a question about the standard functionality, someone else could help you.
And you use some "left" component: "jack:feedback.main"
You never know what this "Jack" wrote in his code.
