MediaBrowser Wrong Default Displayed

Hi
I have been using ServiiGo on a tablet to view my music artwork with limited success.
ServiiGo claim the limitations are from Serviio not themselves.
I have then trialled the MediaBrowser for displaying my music artwork which has the same issues so, ServiiGo are perhaps onto something.
The problem I have is with the folder view. By default this is displaying the 'Back Inlay' image, or otherwise apparently random!
I have no idea why 'Back Inlay' takes precedent over 'Back' but it does. So clearly the image displayed is not sorted alphabetically.
I want to display 'Front'; not an unreasonable request when viewing artwork: when was the last time your local music shop displayed everything back facing frontwards?
I have tried '01 Front' and 'AA Front', but the 'Back Inlay' is still the default display.
Where are the settings for this control, and how can I change them to something more reasonable and expected?

Hmmm.
Charging for a service then refusing to support it is the ultimate rip off!
I guess I'll have to find a streamer that works and is supported!

ServiiGo is not provided or supported by the Serviio developer. You need to contact the provider of ServiiGo for assistance. I don't use the app, so I don't know if the app offers any way to contact the provider. The only way to reach the provider through this forum is in his specific thread: viewtopic.php?f=17&t=6803
