Hey, welcome to the forum!
For Heatmap we did put out an update so press the icon and resync cloud, then re-ping the game and the servers should show. For the Geo-Filter that polygon is fine but filtering mode is disabled, do this instead:
Quit the application/game/client completely
Remove device from the Geo-Filter
Give PC PlayStation Device Type in the Device Manager (if on PC)
Resync from the Geo-Filter Map menu
Re-add the device to the Geo-Filter with the manual option
Set up the Geo-Filter how you like
Wait 2 minutes
Boot up application/game/client
