The "Archive Thread" Button is Missing and Now All I Can do is Close Threads on PC App

Title says it all. For some reason, the "Archive Threads" button has gone missing and I don't want to close all my threads because my friends need to be able to unarchive them at will which they have trouble doing when they're closed instead of archived. 1: Moderator has to do it (they all have the permissions to do so which usually circumvents this issue but it has cropped up before that I (owner and only moderator) had to do it for them). 2: When they're closed, they have a nasty habit of just disappearing and only able to be found via a direct link or searching their name, which is not easy to do during RP.

Sidenote: If Discord isn't supposed to be doing what's described in 1 and 2 then that's unfortunate because it means my app is having a problem. If Discord is doing it's job and working just right regarding 1 and 2, then I'm just stupid and any advice to prevent both issues is greatly appreciated.
