Can't disarm traps

I don't know if this is a bug or not but I can't disarm these traps. I can set them off and avoid them but I can't disarm them. Also I didn't catch it on video but on my way out of the place I noticed on the map that it shows up as an armed trap still. I might add that video later if I have time. Again not sure if this is a bug but I feel like if the trap was sprung the red marker should disappear...

Also Auroc doesn't have dark vision as a half orc.
