[Elecraft] KX3 build question

[w4sec at windstream.net]

I am in the final assembly of my Kx3, And it appears that the KXFL3 is keeping that corner of the case from "completely closing (by just a little bit)- as in both sides bottoming out, where the thumb screw comes in contact with the to chassis. . With the FL3 removed, it closes completely. I have trimmed the cutout fingers from the edge of the fl3. It does seem to close well enough, but just not all the way. Is this a concern, or am I good to go?
Thanks and 73s,
Pete
