I have a copy of the mod that can be blueprinted + copy/paste if you'd like. Optionally, you can edit circuit-gate_0.0.1\prototypes\entities.lua and modify the line "decider.flags = " to:
decider.flags = {"placeable-neutral", "hide-alt-info", "not-upgradable", "placeable-player", "player-creation"}
and further down modify the line "control.flags = " to:
control.flags = {"placeable-neutral", "hide-alt-info", "placeable-off-grid", "not-upgradable", "not-in-kill-statistics", "not-deconstructable", "placeable-player", "player-creation"}
What is missing is the "placeable-player", "player-creation" flags which make it work with blueprint/copy+paste
