WPGMZA_localized_data URL issue

This plugin was used on https://gesparc.ca/.

We’ve recently moved the website from https://gesparc.volcan.design to https://gesparc.ca/ and changed every old URL we could find still containing the old gesparc.volcan.design domain.

For some reason, when you look at the page source on gesparc.ca, there are still references to the old domain name in this variable :

var WPGMZA_localized_data
default_marker_icon”:”https:\/\/gesparc.volcan.design\/wp-content\/plugins\/wp-google-maps\/images\/spotlight-poi2.png”,

We’ve event took a look at the plugin file and replaced the old URL with the new one as you can see here :

https://gesparc.ca/wp-json/wpgmza/v1/features/?filter=%7B%22map_id%22%3A%226%22%2C%22mashupIDs%22%3A%5B%224%22%2C%225%22%2C%229%22%2C%2210%22%2C%226%22%5D%2C%22customFields%22%3A%5B%5D%7D

This seems to cause delays with page loading and it takes a very long time to load the map markers. How can we make sure that these URLs are updated to the new domain?
