Warning: Undefined array key “advanced_marker”

After updating to the latest version of this plugin, I am getting this warning as text on the page where I have the store locator.

This is the complete warning

Warning: Undefined array key “advanced_marker” in /home/customer/www/nuboard.com.pk/public_html/wp-content/plugins/agile-store-locator/includes/helper.php on line 1923
Search Location

I am using shortcode [ASL_STORELOCATOR] to show on the site.

I’ve tried a few basic troubleshooting steps like clearing my browser cache, but that didn’t resolve the issue. I also updated the plugins.

I’d greatly appreciate any suggestions or solutions to resolve this issue.

Thank you in advance for your assistance!
