Here are the cards in question.
The T206 and Bowman I would say are diamond cut, which is why they weren't graded. Most obvious on the Campanella, where the bottom right border is half the size it grows to on the top right.
The middle one looks like it has a wavy right side.
Submit again, and the first two could get a number with different eyes looking at it. If PSA thought either were trimmed, they would have said so.
