How to remove an extra marker from google maps on a website (website on opencart)?

Question

Google Maps

In the contacts on the site there is a Google map, there are two markers, one is already outdated. I removed the unnecessary address from the contacts of the site, but the marker did not disappear on the map.

I tried this way:
1.Connect to the server via FTP or open the FileManager in the control panel on your hosting and go to the /catalog/view/theme/themeXXX/template/information folder.

2.Open the contact.tpl file in any code editor.

3.The part of the code that needs to be edited is enclosed in iframe tags.

BUT I DON'T HAVE SUCH A LINE IN THE CODE! (the code of this file is below)
