Fiasp Insulin Pen

I currently take Fiasp insulin. However, I am noticing with my current pen it seems to be getting stuck.

I am doing the initial airshot of 2 units before actually administering. Then when administering the injection is not as smooth as it normally would be.

Have any of you had this type of issue before?

Thanks all in advance x

It’s a NovoPen. I always have spares, but I was curious if it’s common with said pens.
