Kmail serverside subscriptions not available

So I have a longtime gmail account on kmail. Serverside subscriptions are enabled. I have selected the spam folder so I can see what gmail has filtered.

I added a new gmail account to my kmail. The inbox is fine. In the advanced settings serverside subscriptions are enabled. There are no folders listed.

On my phone I can see all the gmail folders for this account.

Is this a local problem or with the IMAP server?
