DeleteMarker command only clearing global channel, user markers

[zakiechan 11]

Having issues with some code im working on.

I want to be able to wipe all map markers, except for a few I have white-listed during various points in the mission.

All code is run on the dedicated server, using the deletemarker command I cannot delete any user placed markers that are not in global channel.

client side event handler:

"makeAddActionSaveCurrentMarkers" addPublicVariableEventHandler
{	
	private ["_sign", "_passedContent"];

			_passedContent = _this select 1; //form [signObject]
			_sign = _passedContent;
			_sign addAction["<t color='#FF0000'>Save all Current Markers</t>", {  

			//code that runs on addAction
			playerUsedSaveCurrentMarkers = true;
			publicVariableServer "playerUsedSaveCurrentMarkers";

			}, 0, 4];

};

serverside eventhandler:

"playerUsedSaveCurrentMarkers" addPublicVariableEventHandler
{	
	whiteListedMarkers = allMapMarkers;
};

ServerSide Code to delete non whitelisted markers:

{ 
if ( !(_x in whiteListedMarkers) ) then
 {
 deleteMarker _x;
 };
} forEach allMapMarkers;

I am assuming my problem is locality.

If anyone has ideas or prior experience with such an issue your help would be greatly appreciated!
