trunk-recorder conventional analog - log showing 6 recorders (0-5) but only configured 3

[WD0JB]

As the title indicates, I have 3 analog recorders configured, but the log looks like it has 6 recorders running. 3 inactive (A0-A2), and 3 active(A3-A5). Maybe I am misunderstanding something or have something misconfigured?
