Cubase 13 having trouble with Kontakt 6 wallpapers

I recently upgraded from Mojave to Catalina but decided to go back to Mojave.
Although the downgrade was successful Kontakt is fine in stand-alone but in Cubase, it seems to have lost all its wallpapers (artwork). The instruments are there but no wallpapers. (Stand alone)


Help would be much appreciated.


What we see, are different libraries in the standalone Kontakt and in Cubase.

The libraries come from Kontakt, Cubase has nothing to do with Kontakt libraries (they are black-box for Cubase).
