Sort Order from Minimserver

[Budgie]

Hi Simon,
Not sure if it is my configuration of minimserver or my control app bubbleDS but while the order in my NAS has the files in alphabetical order, what I see when browsing with bubbleds control app in folder view is an order I cannot recognise or analyse.

It is possible my tagging is slightly screwed but why I am writing is to ask what is the best order for debugging the problem. Where should I look first and how should I use debugging tools that are built in please?

My setup is all on lan with Qnap NAS serving my multimedia sound files and various renderers, usually a LinnDS on the same subnet.
Control point is bubbleDS on Samsung android phone.
All systems and apps are up to date.

Grateful for any advice when you have a moment. System working but browsing in folder mode not using tags is when the problem arises. Strangely I think the tags are working as required but of course I cannot easily find if any works are missing. The folder view is where I am having the problem.

Regards
Budgie.
