Please note that validations must approved by our Moderation Team first, which may take a few days. It then needs to be approved by you before it will appear on your profile. If you are using the app you can find your pending validations via the Menu 
> Settings 
> Profile & Settings > My Lists > Validations > Pending Validations > click 'approve' next to the validation you want to approve.
On the website, you can visit the top-right account management panel, drop-down to open your panel > My Lists > Validations. If the validation hasn’t appeared in your pending validations within a week, it has been rejected by our Moderation Team. We may have deemed the validation inappropriate for view or invalid.
