Editor: Materials almost always remap to "--_mat"

Not sure if this is me being dumb or actually a bug, but pretty much ever since I've been mapping "wood" to
"ind_metalplates" on "race_rally_start_finish" and "race_wood" on "race_rally_finish_checkpoints"

I might have fixed "race_rally_start_finish" but I'm not quite sure...

My issue is for "race_rally_finish_checkpoints". I keep leaving the game to make sure the material actually worked, yet it rarely did. It seems to want to change to "race_wood_mat" or "ind_metalplates_mat".

Expectation:

Reality:

Here's the items and mapping in Material.cs

Code:

singleton Material(douglas_rally_start_finish)
{
   mapTo = "race_rally_start_finish";
   diffuseColor[0] = "0.992156982 0.992156982 0.992156982 1";
   colorMap[0] = "levels/rallystage/art/shapes/misc/race_rally_start_finish_d.dds";
   normalMap[0] = "levels/rallystage/art/shapes/misc/race_rally_start_finish_n.dds";
   specularPower[0] = "1";
   pixelSpecular[0] = "1";
   annotation = "SAND";
   materialTag0 = "beamng";
   specularStrength0 = "0.588235";
   materialTag2 = "Natural";
   materialTag1 = "rally";
   specularStrength1 = "1.76471";
};


singleton Material(wood)
{
   mapTo = "race_wood";
   colorMap[0] = "levels/rallystage/art/shapes/misc/wood_d.dds";
   normalMap[0] = "levels/rallystage/art/shapes/misc/wood_n.dds";
   specularMap[0] = "levels/rallystage/art/shapes/misc/wood_s.dds";
   specularStrength1 = "1.76471";
   materialTag1 = "rally";
   materialTag2 = "Natural";
   annotation = "SAND";
   materialTag0 = "beamng";
   specularStrength0 = "0.588235";
};

singleton Material(wood)
{
   mapTo = "ind_metalplates";
   colorMap[0] = "levels/rallystage/art/shapes/misc/wood_d.dds";
   normalMap[0] = "levels/rallystage/art/shapes/misc/wood_n.dds";
   specularMap[0] = "levels/rallystage/art/shapes/misc/wood_s.dds";
   specularStrength1 = "1.76471";
   materialTag1 = "rally";
   materialTag2 = "Natural";
   annotation = "SAND";
   materialTag0 = "beamng";
   specularStrength0 = "0.588235";
};

These are the items I'm hoping to fix.


P.S: During this, I restarted the map and now it's mapped correctly. My amount of confusion is through the roof, and I'm getting annoyed with this. Really hoping this is my stupidity's doing...
