What camera that you are having problem with those flashes?
Will switching the two have the same problems.
Make sure it is fully pushed forward into hotshoe & locked:-)
Try shooting second current, this will save you the repair costs.
Your exposure compensation was set to zero, but was your flash compensation set at zero?

SOURCE: How to restore factory settings
To reset the C.Fn settings on the flash just go into C.Fn mode and set each setting to 0.
If there is no C.Fn icon showing, the flash is at it's factory default setting.
Hope this helps :)
