Unable to close changes.

Unable to close changes.

Before, I had a simple open/close options in ServiceDesk Plus.
Now, seemingly after an update to ServiceDesk Plus version 9.0 Build 9041, all of a sudden I have a LOT of 'change options'. Except for the most important one: ' Close'.
I cannot seem to find out how to just close a change.
Am I not seeing the obvious? What am I missing?
Thx.
