elevation profile not working for a particular journey and misc questions

Hey,

https://cycle.travel/map/journey/847174

For this particular journey, the elevation profile is not working. I'm wondering if it's caused by some bogus data in OSM? It's working on my other journeys it seems. Would it possible to add the climbing and descent value in the "Route summary"? It would make it easier to have all the data without clicking a button and having the details taking quite some screen estate.

Since I already created a post, I thought I would mention it: would it possible to remove on https://cycle.travel/map and on https://cycle.travel/by/{name} the "Become a supporter" banner when the account is known to be a supporter?

BTW, I found the url https://cycle.travel/user/profile in a post in this forum. But I can't find anywhere a link to it, whether on the default page, or map, or by/{url}. Am I missing it?

Thanks!
