Translating empty strings in lokalise

In lokalise, there are several strings like these in the image


that appear to be empty. Should I translate them to my local language or keep them as they are?

if theres not translation will take the default , so you dont need to translate those

Since the strings are marked as ‘Unverified’, should I mark them as verified or copy the source to the translation field?

I guess it’s probably just a bug in the upload script, and it probably makes no difference what you do with them, I doubt they are used.

Those don’t seem like valid keys to me.
