I copied those three records to my local dns server and I'm getting the same. It seems because the adobe TXT records is blank so without a subdomain and not linked to the main domain(@). I'm getting the idea that it then sees it as a match request for the previous and therefore giving two answers. I'm not a dns expert but that's what it seems like to me, I've never seen a blank record. So in my idea looking at your configuration your ns records should start with @ as well since that stands for the main domain, as well as your mx records and spf/txt record. So I would change all your records that aren't a subdomain/blank to start with a @ meaning it's a record for your main domain.

When I do it like that on my local dns server I don't get two answers back when requesting the txt record for: asuid.www.intercorp.com.pe
