New to vine, is this normal?

I'm only about a month into the vine program. I've reviewed 10 items so far but two of them always say Not Reviewed Yet. If I click on the review button I can see and edit the review I submitted and I can hit submit again. It's been 14 days for one of the reviews and still shows this way.

Is there something wrong with my review that's keeping it from being approved? Or is this normal and I just need to wait longer?
