Training REMOVE TRAP from NPC (PROBLEM)

Hi there,
I have a big problem with training Remove Trap from NPC (Tinker or Thief).
On the NPC's list the skill is named Disarming Traps, in skill list Remove Traps.
Nothing from the commands works. I've tried:
xxx train remove trap
xxx train remove traps
xxx train removing trap
xxx train removing traps
xxx train disarming traps
xxx train disarming trap
xxx train disarm traps
xxx train disarm trap

Nothing…. Help!

you must have the pre-requisite skill levels (detect hidden/lockpicking 50 each) before you can train

I'm Having the same problem as Herbaciarz, tried various commands nothing works Grrrr!

My Remove Trap Skill is unlocked and arrow up, Detect hidden at 98.4, lockpicking at 94.6

I'm around 630 points real total.

No spaces

Removingtraps
Or
Removetrap

Maybe?

try train remove

Thanks Con con con con, and Wylwrk. Train Remove worked.

I needed 50 detect and 50 REAL skill in LP before she would prompt and only "[npc name] train disarming" worked
