Google has recently made it so those POIs are always clickable. They’ve refused to fix it, you can see the bug report here if you’re interested.
One workaround is to use a styled map to hide the business POIs. Google’s own styling tool allows you to select POI layers and hide them. Please see the MapPress documentation for more information about how to enter map styles in the settings.
Then scroll down to the css setting and from the drop down select your class name and apply it. Click save on the settings… the poi premium lists no longer appear.
