Flash only working in slave mode? :/

[DGMPhotography]

Hey there,

So I have two Yonguo 560iii flashes, and they're great. However, apparently one now doesn't work with the remote.. it only seems to work in slave mode, having the other one flash from the remote. It's not debilitating, but it's really annoying.

Any thoughts/fixes?

when my 560ex misbehaved I tend to go through the steps and reset the config, even though I swear it's the same config.
Now that I have it on a radio trigger, I just have it set to Manual as I use it as my BG flash. It's been less troublefree this way.
