Connect and disconnect individual components

I am new to Voyager. According to the user manual, as of Voyager 2.0.14e, buttons to connect and disconnect individual components have been added at the far right of each equipment line. However, the only button that is available for me to do that is the Planetarium button. Am I missing something or doing something wrong?

I was wondering the same thing myself, but I did some searching on this forum and found that it was already asked here about a year ago. From it, it is a feature they are working on but haven’t fully implemented.
