Upon joining an instance group with the new dungeon LFG tool in WotLK Classic, the "eye" bubble that gives options to teleport in/out of the instance and leave the instance group does not appear in the carbonite sidebar. Requires disabling carbonite and using standard minimap eye to drop group after completion.

Myself and 3 other family members are also having this issue.

Solution:
In NxMap.lua Line 10531. Add ["MiniMapLFGFrame",] to the end of the string. This adds LFG icon to variable [local mmOwnerNames]
Below is the full string modified.
"NXMiniMapBut","GameTimeFrame","TimeManagerClockButton","MiniMapWorldMapButton","MiniMapMailFrame","MiniMapTracking","MiniMapVoiceChatFrame","QueueStatusMinimapButton","MiniMapInstanceDifficulty","GarrisonLandingPageMinimapButton","MiniMapLFGFrame",
