Code signing for VBA problems

I program in VBA for Microsoft Office (.dotm, .ppam, .xlam) add-ins and global templates.  I have purchased an EV code signing certificate from Comodo/Sectigo.  I am able to sign an .msi installer, but I also want to sign my VBA macro code inside the Office file types listed above.  I am following the instructions provided at https://support.microsoft.com/en-us/topic/digitally-sign-your-macro-project-956e9cc8-bbf6-4365-8bfa-98505ecd1c01   However, after I sign the project  and try to re-save it I get the following error message:  "There was a problem with the Digital Certificate. The VBA Project could not be signed. The signature will be discarded."  Sectigo customer support has not been helpful.  How can I get this to work?
