I've come across an issue with the Process Builder, when creating an Email Alert action.

When I try and create a new action it comes up with the following error message: You must specify a name for the action call.

I've noticed that there are a few other people with the same issue, but there doesn't seem to be a resolution to it yet.  https://success.salesforce.com/answers?id=9063A0000019Sv2QAE

Has anyone else come across this?
