When you craft the Distillation Tower capsule, a bunch of error line appear in chat:

If you put the capsule that you crafted into the inventory, the game immedietely crash
The capsule in JEI doesn't crash the game when inside the inventory
Edit:
The crafted capsule can't deploy the multiblock:

The JEI capsule can deploy, but cannot undo:

The crafted capsule's doesn't have steel scaffolding slab in requirement:

JEI capsule has normal requirement:

Also, the capsule that the quest give is unusable, and has spelling error:

It seems that it is not possible for crafted blueprints to contain slabs. However, the quest has been fixed to contain the original capsule which seems to work with slabs just fine in 3.2.2, so it shouldn't be a problem for people using the quest reward's blueprint.
