You'll see, when I have my Selectric keycaps lying on my desk, they look something like this:

Buuuut, when they are on my beamspring, this thing completely fucks up and the keycaps are like this (it's the same with the original keycaps too):

Am I missing something? Is this desired and normal? I wonder which one of the profiles is the correct, or if even both are correct. For example, I can tell by the pictures that SA keycaps have the "type 1" profile, when my NMB keyboards clearly have the "type 2" one.
I also would be glad to hear about other profiles that you like. Thanks.
