*NO FOLLOW UP* Sample browsing problems

[ollim]

Firmware V1.14a.

I have put a lot of samples in different folders in the sample folder.

Like this:
"000_Kick" with 16 raw sample files
"001_Kick" with 287 raw sample files (named from "Kick0001.raw" to "Kick0287.raw")
"010_Snare" with 20 raw sample files
"011_Snare" with 278 raw sample files (named from "Snare0001.raw" to "Snare0278.raw")
"020_CHH" with 4 raw sample files
"021_CHH" with 136 raw sample files (named from "HH0001.raw" to "HH0136.raw")

If i browse in these folders, i get weird results:
"000_Kick" - all 16 files are displayed
"001_Kick" - only 31 files are displayed ("Kick0001.raw" to "Kick0031.raw")
"010_Snare" - all 20 files are displayed
"011_Snare" - only 22 files are displayed ("Snare0001.raw" to "Snare0022.raw")
"020_CHH" - all 4 files are displayed
"021_CHH" - all 136 files are displayed!

So in my "001_Kick" and "011_Snare" folders only a part of the files are displayed.
But in the "021_CHH" folder all files are displayed.

What is the rule behind it or what can i do, so that all files in all folders will be displayed?
