I have the ghost version of this, which looks identical to your pics, and I have the same issue. It will drop and seem like it has the correct drop speed selected, but it will catch every now and then. I know the line can get wrapped around funny if you let it have slack but I don't think thats the issue. When dropping with a tight line it just suddenly rebounds. I usually feed it past those points wiht my hands and it starts falling again.
Might be the reel or might be me.
