A couple of dive computers will import all gases that are configured, even if you never switched to them. And if you have a default cylinder configured in Subsurface, then this turns into these ghost cylinders.
One reason libdivecomputer usually returns all configured gas mixes is because (as Steve mentioned) some users want to see those unused mixes. But it not always consistent, and depends on the backend implementation (*). Maybe it would a good idea to include an enabled/disabled flag to give a bit more information to the application?
Whether a gas mix is used or unused is something the application can already detect by looking at the gas switches in the samples. But the enabled/disabled state (if present) is not something that is exposed now.
(*) For example the iconhd backend discards disabled gas mixes, but the ostc and ostc3 backends does report them.
