"IMatch standard categories" lost

[PoeschelA]

Please, how do I get the "IMatch standard categories" back?
I have done something, but I can't find my way back.

Use the Category import in the Import & Export panel and re-import one of

"C:\ProgramData\photools.com\IMatch6\Presets\system-en.imcsx"

(English category names) or

"C:\ProgramData\photools.com\IMatch6\Presets\system-de.imcsx"

(German category names)
