@Mansinagpal08 I made the same mistake as you and I got my ppr with the correct name format. My biometrics got updated after 85 days I.e. just a day before my ppr. So don't worry, just raise webform and wait.
Can you put your details and check the biometrics? https://onlineservices-servicesenligne.cic.gc.ca/extapp/bioStatusQuery
I initially entered my first name as my last name, and it showed. Now when I enter the correct last name is showing. Looks like they have made some changes.
Yes, I would say go ahead with biometrics. In the centre, they will enrol with the correct name format; After that raise a webform and explain IRCC. Your biometrics on the portal won't get updated until the name is in the correct format. However, you can see your biometrics number and validity...
When do you have your biometrics? Go ahead with your biometrics and then let them know about the mixed names then raise webform after biometrics. I'm waiting for a month still my names are not corrected.
Can you please tell me when did you submit your application? To which office did you raise webform Delhi or Baganlore? After how many days did you get a reply? Please tell me as this would help me. If your medicals got updated soon you will get ppr.
