Load json fails when change dataset on nextstrain

Hello nextstrain team.

It’s hard to explain so I give you example.

if you access “auspice” page and change A to B then fails.

Obviously,
I need to set one of F/G/WGS below /rsv/B/.

but you can see below works.

if you access “auspice” page and change europe to global then it moves to “auspice”.

can you tell me how to do it.

This is a known bug but we haven’t managed to fix it yet. Note that changing the last part (G/F/WGS) does work as expected. (That link has an explanation of why it happens if you’re interested, as well as why it doesn’t happen for our core datasets such as /ncov/....)
