Picture please.
I too would like to see if it is a film over the filter or if it's something that got sucked in, because I've never bought air filters that were wrapped in plastic. My Kubota, JD, Case, Ford, Donaldson, Cat's all just come in the box.
And yes, an air restriction will cause more frequent regens.
Well, one post from the OP and he's been absent. I think we need to see a pic to really know what's going on.
