Glitch with the spawners

So when I create a spawner, it is invisible. I understand it binds it to the blocks you are looking at when you create it. I use /mm s set <name> showflames true and it correctly displays there is a spawner there.

However, /mm s set <name> breakable true does NOT work. I have toggled that on and when I break the block it just breaks the block and leaves an invisible spawner.

Also, can we get some interaction with the WorldSchematics2 plugin. I have set it in the config over...
