Summoned custom Armor Stand creation with command block, can't remove it?

So I'm a little late to discover the mrgarretto armor stand generator. I was attempting to make or find some furniture for my house. Found a couch I liked the look of and decided to place it in my world to see how it looked. Didn't stop to consider that I am a total newb when it comes to this sort of thing and can't figure out how to remove it. To clarify, the destroy command does not work:

execute @e[type=armor_stand,name=AM_VRXpaX_M] ~ ~ ~ kill @e[tag=AM_VRXpaX,c=34]

Here is the ridiculously long command for the couch itself, if that's helpful:

Your command summons armor stands and villagers.

Go stand next to the couch and run these two commands:

/kill @e[type=armor_stand,r=5]
/kill @e[type=villager,r=5]

Be careful if any villagers or armor stands that you care about are in the same area. If need be, you can reduce the radius within the commands.

You may also want these commands to undo other things that command did:

/scoreboard teams remove noColAM_VRXpaX
/gamerule commandBlockOutput true

This has been tested:

One last thing, a suggestion. Make a new world to test things like your command. This way you can delete it if you really mess something up. It removes the risk of damaging a world you play and care about.
