Help with PSA case defect?

Hi all, I was hoping someone could shed some light on an abnormality with a PSA card I purchased recently. There appears to be an issue with the PSA case but I am not 100% certain that this is an issue with the case as it could be damage on the card itself. If anyone has seen this issue before with a PSA case please can you let me know. The issues is the light rectangular section I have attached a picture of it here:

The white rectangular spec is a common defect in tens of thousands of PSA slabs. Your card is perfectly fine.

That’s a massive relief I was scared that my 1st Edition Base Set Charizard had some damage. Cheers for the insight @melchior.

I have the same on a few cards. At first I freaked out, but you can tell it’s on the case because if you can move the card (they’re not always completely snug in the case) then you can see the rectangle doesn’t move with it.
