MX records resolving into correct domain name

I have updated my mx records as following mail.prevara.tech but then my outlook stops working and when I checked the DNS status in intoDNS: prevara.tech - check DNS server and mail server health it shows the mx records as the wrong hostname
_dc-mx.e74b5fa5ea54.prevara.tech. Can someone help me on this one please?

yes i resolved it myself, the A record was proxied and when I changed that to DNS only, it got fixed
