Tour Ideas - Paved

A fantastic resource Richard and I've used it for many trips and tours. 

I've started looking at Suggest A Ride --> Tour Ideas' but the routing button keeps reverting to 'Any' from 'Paved'. Selecting the route you can then click Paved and it will modify, but I wonder why its not possible to keep the routing button on Paved to see the selection of route suggestions as in paved routing in the first place? Not a great issue, but is it intentional? Thank you.
