How do I enable merge note types on Anki on Mac?

I’m attempting to import the Anking Deck, but I keep getting this error message. Can someone direct me as to how to enable merge note types on Anki Version ⁨23.10 (51a10f09)⁩ on Mac?

Thank you in advance

Since there was no response, can only recommend sharing to anking community which the question belongs

Not sure what this merge notetype function is on anki

Ankihub does not support 23.10 yet, so downgrading might be necessary

It’s in this screen shown before the one in your screenshot:
