Good catch!

"use the first one" -> "using the first one"

However I'm wondering if this is the right behaviour. What if the user realises they actually wanted the second one? Given it's a warning the finish operation would have proceeded and the user will have to clean things up manually. Rather than a warning, should we in fact be erroring out and requiring the user to be more specific in this case?

Cheers,
Paul
