Problem with Meta Pixels settings. Errors: The Facebook pixel activated 4 times on this web page, which can cause errors in you event tracking

I connected Meta Pixels to the site, through the settings using ID pixels. On the page https://www.berlinballet.company/techno-ballet a third-party ticket purchase widget is used, which also uses pixels. The widget is inserted into the page using the code that was taken from the ticket purchase service page. In the same ticket purchase service, I configured pixels (also using ID) so that I could track ticket purchases. The site has 4 ticket purchase widgets for each date, and pixels are configured for each widget. The problem is that for some reason pixels is triggered 4 times, not 1 time (which is exactly the number of widgets inserted on the page). Here is the error in pixels: Problem with Meta Pixels settings. Errors: The Facebook pixel activated 4 times on this web page, which can cause errors in you event tracking

What could be the problem and how to solve it?
