Missing hops

[Wurst Brauerei]

I recently used Yellow Sub hops and noticed they are not in the hops list at

https://www.brewersfriend.com/hops

but they do exist here

https://www.brewersfriend.com/hops/yellow-sub/

What's the reason for them being in the database, but not shown in the hops list, or any of the ingredients dropdowns for that matter?

Thanks
