I'm admin and cannot update "Swimming and medical fields"

I am a Troop admin, yet I cannot update one of our scout’s info.
AFIACT, there are no latent issues regarding mobile number as described in Swimming and medical fields editable by admin only.

IA is currently significantly impacted by the API issues. I don’t know that this is a symptom for certain, but it seems like it’s tied in with other access issues.
