Double Insulators on injectors?

Double Insulators on injectors?

So i took my fuel rail off today and we messing around with some stuff and when i went to put it back on i realized there were insulators still on the bottom of my injectors and also 6 still in my intake manifold.... Is this normal?  Or did the previous owner buy the wrong size injectors and make them work by adding an insulator? When i remove one set of insulators the Injector does not seat in the intake manifold where its supposed to...

heres 2 pictures of what i mean

This is not normal. There should only be one insulator

i went ahead and ordered all new Insulators and both sets of upper O-rings. I think they all might be slightly squashed
