Parameter does not work: "dir": "ISO", "class": "Super_1"

[BKPB]

I have three images in the "ISO" folder .iso, 
Windows_7_&_10_Pro_x86_x64_30.05.2021.iso,
Windows_7_Pro_x86_x64_15.12.2021.iso,
Windows_10_21H2_19044.1766_x64.iso.
I assigned the Windows_1 icon to the last two, and the image Windows_10_21H2_19044.1766_x64.iso.
I want to assign a Super icon_1. 
But I can't do it. Tell me where the error is, what am I doing wrong?
