| SteveB,
Your Paph is behaving normally. New growths in Paphs come from the base just like you're seeing. Many people think Paphs are monopodial like a Phal because they see leaves growing out of the crown but Paphs are not actually monopodial like a Phal but instead are sympodial like a Cattleya or Dendrobium. They grow a new growth which matures and blooms then that growth grows no more and a new growth starts from the base.
I see you're in Canada so you're headed into Autumn. The cooler days will probably mean the new growth will slow down a little.
Cheers
