Cant add single rider time since update

Since the new lines update on iphone, i cant add single rider times. I even find the posted times not always to be correct. Standby works fine.

When I go to single rider the scroll bar remains on add, cant go next only backwards and if I do it, it adjusts standby time.

Very annoying because some times arent really real time. 8 minutes on gringotts turned out to be 20 and I could not adjust.

Somebody else experiencing this?
