duplicating a spline loop

hey all. REALLY hope someone can help me here because im losing my mind and google isnt helping. I have made a platform loop a circle using a spline path. i want 4 of the same thing but for some reason whatever i do i only see 1. ive tried duplicating the whole thing, tried replicating the 1st one, tried using a child blue print. but niothing seems to work. anyone able to give me an idea of what im doing



wrong?

as you can see in the pics i have 4 loops set up but when i test the play only 1 shows up. ive tried everything i can think of and im getting really annoyed that something i bet is so simple is causing me this much hastle haha
