Hi @Sukain 
Happy New Year and thank you so much for reaching out to the HubSpot Community!
We’re excited to see you progressing with your Digital Marketing journey! At this time, we’re unable to regenerate the certificate, but we’re here to help with any other questions or support you might need!
1. Could you please check the solution from @JorgeFuentesZ on this similar post “Update name on certifications”, mainly these 2 points:
- “Log out and back into your account to see if changes are reflected.”
- “Also, make sure that these updates are being done on the same portal you’re using to do the Academy certifications.”
2. Can you also have a look at this article “How do I change the name displayed on a certification?”. Have you checked the following:
“To check your certification again:
In your HubSpot account, click your account name in the top right corner, then click HubSpot Academy.
At the top of the Academy dashboard, click the My learning tab.
In the left sidebar, navigate to Completed. Your completed courses will display on the right.
To view a certification, click View certification. The certification should display the updated name. If the updated name isn’t displaying, wait a few minutes, then refresh the page and check again.”
Let us know if that works please?
Have a brilliant day @Sukain!
Bérangère
