"Face features" blank for existing faces


On the phone, why is the “face features” section blank when I open faces I’ve used on previous versions of Facer?


I’ve edited this because, with a bit of playing round and further ‘research’ I got most of the answers to all the original questions I had. This one remains though, but it’s not very important. To be honest, if I could have found a button to delete this post I would’ve!
