Remove door and bed gone wrong in Dwarf Fortress

I wanted to make a few changes to my sleeping quaters. I had a bed in an office for the bookkeeper which i thought was a mistake, also my mansonry dwarf just constructed a master quality door, so i figured i would remove the door to his bedroom and replace it with the new master quality one. Figured he'd appreciate looking at his own masterpiece every day more than anyone?

I figured i would need to remove both with q-x. So i did the door first. It seemed to work - some dwarf came for it and picked it up. I paused the game and marked the bed as well. I unpaused. The door-dwarf dropped the door on the next tile, and while i was sitting waiting for him to pick it up again and move it further i saw someone was comming for my 'office bed'. Instead he picked up the table in the office and left the bed.

I don't know what to do now. I tried to d-b-c (claim) on the door but it didn't work. Also i can't seem to target the bed for removal any more.

1) Is this normal or did i run into a bug? How can i get back to normal? 2) Bonus question. I tried placing the master quality door in the hallway but it doesn't let me pick the quality door - how can i select that specific quality door?

UPDATE: I figured out how to select the quality item: Before selecting the type of door (pressing enter) you can press 'x' for expand - then you get the list of items...
