Issue Accepting Microsoft Partner Agreement

Hello, having an issue accepting the cloud partner agreement while enrolling in Partner Center.

I am currently applying for our company's driver signing permissions on Microsoft. While filling out information on the following webpage: https://partner.microsoft.com/en-us/dashboard/account/exp/enrollnow/partner, I encountered an issue. When the webpage pulled our company name from Dun & Bradstreet, Microsoft deemed our company name invalid. I noticed that there is a comma in the name, as shown in the screenshot.

However, when we applied for a signature from DigiCert, we used the same company name with the comma as the signing name.

Therefore, I cannot remove the comma at this point because if I do, Microsoft might reject the signed certification file later due to a mismatch in the company name. Could you help resolve this issue?
