I guess I don't know how a removed (old) label left a white 'base' underneath unless it was an incomplete removal or there is white matrix under where the original label was.

re-reading your reply to
@CardRally above, there's white under where the old label was.
1) That's *not* shrinkage from the
@Gear label. No way, no how. You'd have to be on Arrakis for a year to desiccate the moisture out of a label to shrink it as much as your photo presuming they were cut to exactly fit the previous label space.
2) As much as I love
@Gear and the great work they do, I put this 50/50 on them as well as yourself for this. They should have realized these chips have an 'undercoat' that doesn't match the base color of the chip. At the same time, pulling an inlay from the chips you are going to re-label
before doing the job (if not just an over-label) is also partly on the person modifying the chip. I've only over-labeled yet had to have a set of
@Gear labels re-done because I didn't bother to test-drive a design I wanted with a test print on my lousy printer at work to know they wouldn't turn out as well as in my mind (or on screen).
That said, any over label
has to fit in the old recess and because people aren't robots, there
will be a smaller cut made to allow imperfections in label placement in the old and subsequently larger space afterwards. Don't expect a 1:1 replacement....
3) From the photos, the printing goes to the edge of where they were cut out of the base sheet. Maybe this is as simple as a miscommunication as far as what was wanted, but a scaling and cut of the print that's 3% larger than what was cut to fully cover the matrix of the chip seems like that's all that's needed. Again, I'm limited to the photos you posted, but I can't see a cutout that goes into the white of the blank un-printed sheet which looks to my eye like a label that was cut smaller than the recess and therefore the white that's lurking under the old and now removed inlay.
I hope you can resolve this as these will made nice fracs for your set, but to briefly answer your question, there's no way this is label shrinkage, and definitely not for a few weeks in Alabama unless you left the evelope with the lables in your mailbox the whole time. I have re-labled chips in the very dry Arizona desert with the labels parked (inside) for several months and haven't seen any shrinkage at all.
