Unhappy about sons pre-k report card

We got our sons report card, it's more of an evaluation basically. But my husband and I both feel like the teacher pencil whipped the form and I don't know if we should say something, or let it go.

There are 8 categories and about 9 or less things under those categories. The report basically has all "E" marked which means Emerging (inconsistent but progressing) in the box for teacher comments all she wrote was "(child's name) is a fun caring friend. He is always ready for fun."

So the message just seems very empty in itself.

But my main problem is all these E's being marked where I know for a fact he has "mastered"

I don't know if I should reach out to his teacher or just let it go since it is just preschool. He just got a new teacher, and his last teacher had me so excited and confident about starting kindergarten next year. But now I'm feeling a little different. Especially since he is in IEP for speech.
