Hi GeoMuBa,
We were able to reproduce the issue and are working on a formal solution. Thank you for your report and patience.
In the meantime, temporary workaround steps are:
1) Check the "I have read and agree to the terms of use agreement and geocaching hiding guidelines" checkbox at the bottom of the page
2) Change cache type
You should then receive a prompt to confirm that change. Be aware that changing geocache type now erases additional waypoints; this is because waypoint rules vary by cache type and the rules are now being enforced.
Let me know if this workaround works for you. Again, we'll be following up with a formal solution shortly.
Thank you,
