Watch the video and tell me if i did something wrong.
You can record a video too.
Waiting for your response!

Comment 9 Nuria 2019-04-11 06:39:16 UTC

Good morning, I checked in other distributions and the error doesn't play so I guess it will be a version error.
I think we can mark this bug as solved.
Best regards

Brilliant, thanks for checking and sorry for the whole issue!
