Perhaps there aren't many PM only caches near you?
I've just done a Search for all caches near to your first find "D.I.P." - The nearest PM cache I see is "Memorial Day" GC3MA4R, then GC1JD2B, GCZPMB, GC1HEJM, GC3F2AQ, GCXWAY. That's all there are within the 10 miles radius.
Sorry I can't help as I don't use the iphone but maybe someone else can sort it out for you.

Thanks for trying MrsB
"Memorial Day" is actually what had me notice the glitch. I had found yesterday on the computer and headed to the direction of the cache with my iphone and thats when I noticed the iphone wasn't finding it. (I can pull it up if I search directly for the GC# but thats it) I then noticed another a bit away called ""Wash" You Were Here!" GC3F7K3 and had the same scenario where I could view it on the website but the iphone isn't locating it in basic searches. I'm leaving tomorrow on a road trip through a few states and really don't want to miss a good cache along the way.
