Bans from REST API do not seem to apply restrictions

[Alexander V]

There's a message on the user's profile that says they got warned via rest API: Banned

 

But above revoke, it says "No Restrictions Applied", the ban button is still there and they say they can browse the forum as normal. 

I used the POST endpoint for warnings and some parts of the UI (e.g. the ban button) offer different options (no group movings or IP bans, for the ban button). 

But the red banner above their profile in the ACP, stating they are banned, fails to show as well.

I am 90% sure this is a bug in the REST api, and would like a workaround if possible, or an indication it works fine elsewhere so I can start looking into potential causes.

 

With all customizations disabled, the same happens:
