C module 9265 Analog Out open loop fault on index 2 when not being used. How do I correct this?

I have a 9265 AO with an actuator connected to AO0. I am getting a "Open Current Loop" Fault on AO1. I don't have anything connected to AO1 and I am sending 0mA to that channel. I'm also sending 0mA to AO2 and AO3 but I'm not getting the faults on those channels. Why am I getting this fault and how do I get rid of it?

NI says:

"Open Current Loop—Returns an array of Boolean values. A value of TRUE in any index indicates that the channel sharing a number with that index has an open current loop and is configured to output a nonzero current value"
