Hi
PaulineKerketta,
I can help you in correcting the Title/prefix on your certification profile.
Please fill out the
Microsoft Certification Profile Name Change Request form and verify your identity by providing three (3) pieces of personal information that match what's on your Microsoft Certification Profile.
Once this information is verified, your name will be updated in 24-48 business hours.
After completing the form, please send the Support Request Number through the
private message I initiated to make sure that your case will be prioritized.
(please see image below):

To know more about the new process for Legal Name Change requests, you may refer to this
sticky post.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages. Thank
you.
Regards,
