NAS - files saved into first folder only!

I use 4 x G1 Series cameras (minidomes and cube) that save data to NAS. All used to work fine but after upgrading to firmware V5.5.83 I noticed all video files are saved into one folder only. All other folders / disks where camera has access are never updated - they are all 0 size.

I added 3x network shares (NAS) for each camera - 3x 200GB. When camera initializes the disks it creates folders/files structure on each disk correctly. But the files are never written to any other location...
