Madsonic Support

Hello,
running MADSONIC 6.3.9840.8df1ddd.20180107.0710 in FreeBSD 11.0 with Tomcat

This is an example of my folder structure
/Classical/Mozart, Wolfgang Amadeus/Mozart - Premium Edition
./Mozart CD01
./Mozart CD02
./Mozart CD03
./Mozart CD04
./Mozart CD05
./Mozart CD06
./Mozart CD07
./Mozart CD08
./Mozart CD09
./Mozart CD10
./Mozart CD11
./Mozart CD12
./Mozart CD13
...
./Mozart CD40
madsonic_set.tag

This is how is displayed in madsonic when I browse:
[2007] Mozart - Premium Edition - Disk1
[2007] Mozart - Premium Edition - Disk1 - Disk10
[2007] Mozart - Premium Edition - Disk1 - Disk11
[2007] Mozart - Premium Edition - Disk1 - Disk12
[2007] Mozart - Premium Edition - Disk1 - Disk13
[2007] Mozart - Premium Edition - Disk1 - Disk14
[2007] Mozart - Premium Edition - Disk1 - Disk15
[2007] Mozart - Premium Edition - Disk2
[2007] Mozart - Premium Edition - Disk3
[2007] Mozart - Premium Edition - Disk4
[2007] Mozart CD01
[2007] Mozart CD02
[2007] Mozart CD03
[2007] Mozart CD04
[2007] Mozart CD05
[2007] Mozart CD06
[2007] Mozart CD07
[2007] Mozart CD08
[2007] Mozart CD09

The displayed album names does not correspond with the folder names or the tagged album names, for example "Mozart - Premium Edition - Disk1" points to folder "Mozart CD18" and "Mozart - Premium Edition - Disk4" points to folder "Mozart CD40". However from "Mozart CD01" to "Mozart CD09" the information is correct.
Same with other big sets.
