When I first installed IMatch, I selected "German" as the language.
After that I changed the language to "English".
Unfortunately, the change to "English" was not consistent.
So there are still places in IMatch where the language is "German". E.g. ExifTool.
Is there a way to change everything to "English"?
Example?
ExiTool.
That's normal.
These settings are created once, when you first start IMatch. In the language that is then current.
Changing the UI language does not delete settings or anything. This would be really bad - catastrophic even.
Just rename the presets in any way you wish.
The same is true for other things, like the Standard IMatch categories. Rename them or drop them and re-import them as needed.
