I would say:
1) Cards may not fit their holders all the time.
2) Card is probably not trimmed.
3) We are way outside the return window.
4) Not enough information.

Way forward: if you are concerned about the card being altered, inspect it yourself for trimming (bat ears, unusual cut, etc) and if you can find some, send it back to PSA under their grade guarantee by submitting for a review. If PSA says it's now trimmed, they owe the difference between an altered and a true card in that condition.
If PSA says it is not trimmed and reholders it with a current slab, they may use one that now fits the card better so the shortness in holder effect is no longer evident.
