@Davidsastresas how is your schedule? - back in February I think this was number 6 in your queue. :)

Sorry for taking this long @AndKe. I was still busy with other ongoing projects but I spared some time to fix this one:

#10678

It turns out to be a bug where QGC was expecting to have terrain data on the surveys if these had terrain frame. The behaviour you showed in your video was only present when this terrain info was not present, with terrain info the survey was generated correctly, so I pulled that string and it turns out that was the reason.

Thank you very much for reporting this, and sorry for taking this long to address it. Let me know how it goes, and if it fixes the problem for you please close the issue and comment on the PR. Thanks!
