Don't take it too literally - you're not doing anything wrong. If you've phoned for PPR or have filed a plan I'll have a strip. If you haven't then the addition of that word inbound means I pick up a yellow one and can sort you out as far as gettting you in.
The only reason I said pre-written is that my airfield is meant to be PPR by phone - but it's no great problem if you forget to do that.
