ORF RAW file unreadable after altering with exif tool (imatch 2020)

[Mac2]

I just came back to this and implemented the suggestion by Phil.
IMatch now explicitly excludes make/model from being mapped back from XMP to EXIF via this sequence in the args file:

...
v:\exiftool\arg_files\xmp2exif.args
--make
--model
...

The output produced by this now retains the original additional blanks and spaces in the make and model name.

I've then installed an evaluation version of SilkyPix for testing.
SilkyPix has no problems opening files with metadata updated by IMatch. But it also has no problems with the original file modified by IMatch (with the blanks removed).
I assume that the version of SilkyPix I've used (10.0.8.0) already contains the bug fix and they no longer rely on a specific number of blanks in the model name.
