Simple "Go" and "Back" macros: trouble with "Back"

On my Ion, I want to write simple "Go" and "Back" macros to trigger whatever cuelist I have loaded on the master fader. I want to use these as events so the gaffer can hold a little two-button momentary switch I made and trigger and back a cuelist via the analog input. Got the "Go" macro to work fine, just by deleting the cuelist number (which automatically populates) in the macro editor. It reads, "Go_Cuelist Fader Master_User". However, the "Back" macro, recorded similarly, doesn't work. Just recording a "Back" command live records a "Back" command in the macro, that doesn't trigger it, I tried adding "Fader" and Master_User" commands after, that also doesn't work. Suggestions?
