More Fields: Input “Values (if applicable)” is disabled

I am using this plugin since a day and I noticed too, seems it is a bug. All you have to do is to choose another meta type in the list, then select the previous type again. And the field is enabled !

Now, I try to understand, if it is possible, how to give a “label” for each value…
