Delete -> Not a deletable group: MakerUnknown

[Mike55]

Hello,

I would like to run the following command to delete the MakerUnknown:
exiftool -u -MakerUnknown:all= "bad.jpg_original"

Unfortunately I get the following message:
Warning: Not a deletable group: MakerUnknown
Nothing to do.

Is there any way to delete the MakerUnknown?

Thanks a lot

In the same picture I have the same problem with Huawei:

>exiftool -u -g1 -Huawei:all "schlecht.jpg_original"

Use exiftool -listd to list all deletable groups.  You'll have to use -makernotes:all to do this.
