oled not displaying folder name

[nex86]

Hello,
I'm using a 128x32px OLED for my project,
I want to see at least folder name and image name, I don't need to see the rest.
so I tried specifying:
display-order = '3,0'

for

0: Current image name
1: Status
2: Image/Volume info
3: Current subfolder name

but all I currently see is the image name, not the folder name...

Any idea?

Should be display-order = 3,0

Note no single quotes. The example FF.CFG is more than misleading here. I will fix it!
