Adding the routes by ticking the routes on the crag page I find fairly reliable.
If however, I try to add a route from the route's own page, the pop-up form seems corrupt and doesn't have all the normal options (O/S, RP etc) on the lists. Sometime it will save some info to the logbook and the proper values can then be edited later. Other times it just doesn't save. I've given up trying to do it this way and always just go to the crag page.
