Can't install Deluge

I running an up-to-date QuickBox Pro and I uninstalled Deluge, via Application Management, a few days ago. I decided today I wanted to reinstall it, but when I go to Application Management, the button next to Deluge says “uninstall”. When you click uninstall, it says it’s going to do it, but the button remains as uninstall. I tried rebooting, but that did nothing.

So, as it stands, I can’t install it through the web ui because it only ever says uninstall. I know I could just install Deluge via SSH, but I’d like to resolve this problem so I can install it via the web ui.

Any help would be greatly appreciated.
