Red MX and SRV records, no TXT Records, e-mail unverified

Hello All,
Firstly I would like to say hello to all of you, because I am new in OVH :smile:
Yesterday I bought E-Mail Pro. I own a domain (outside OVH) and I wanted to connect an e-mail to it.
I configured all CNAME, SRV and MX records as it was written in manual in Web Control Panel, but... SRV and MX Record boxes are red. That causes I am not able to proceed to step 2 in MX Record process. Strange thing is that e-mails are being sent and received without any problems.
THe second problem is that I did not receive TXT record to validate e-mail and domain. That causes my e-mail is understood by foreign Mails as spam/unverified/etc.
What should I do?
