the natural spawn of non-native dinos on the island

[SmoshToast 0]

Im trying to have non-native dinos spawn on my ark server (the island) but it wont naturally spawn more than one type of dino at any location. for example I made it so that mantises spawn in the mountains with the code      ConfigAddNPCSpawnEntriesContainer=(NPCSpawnEntriesContainerClassString="DinoSpawnEntriesMountain",NPCSpawnEntries=((AnEntryName="MantisMountain",EntryWeight=0.5,NPCsToSpawnStrings=("Mantis_Character_BP_C"))),NPCSpawnLimits=((NPCClassString="Mantis_Character_BP_C",MaxPercentageOfDesiredNumToAllow=0.5)))     but when i try to do the same thing with thorny dragons It does not work ConfigAddNPCSpawnEntriesContainer=(NPCSpawnEntriesContainerClassString="DinoSpawnEntriesMountain",NPCSpawnEntries=((AnEntryName="ThornyDragonMountain",EntryWeight=0.5,NPCsToSpawnStrings=("SpineyLizard_Character_BP_C"))),NPCSpawnLimits=((NPCClassString="SpineyLizard_Character_BP_C",MaxPercentageOfDesiredNumToAllow=0.5)))       is something wrong with my code?
