However, I think I accidentally placed a spring in the hole to the left of the spacebar. (I purchased extra springs so I had a few extras)
Here is the picture:

What is supposed to be in that left hole? I don't think I'm missing any spacers (ie. under certain keys) so is that hole just supposed to be left empty?
If the spring doesn't belong, I suppose I can just rip it out from the top, right? (I definitely don't want to undo the bolts again!)
