How to Import presets

Hi i’m currently trialing Nik 6 after a 2 year absence due to running an Apple M1 Silicon. I’m trying to import my past presets into SEP, and AEP either using the import function in the plugin, or by directly copying and pasting the .np file into /Users/<user_account>/Library/Preferences/DxO/ (on a Mac) but they are not showing up in the plugin, any idea’s??
