Hi, I've been having the same issue with the trophy's over the last 2 days.
I was advised to report the issue on this Microsoft forum: https://trainingsupport.microsoft.com/en-us/mcp/forum/mcp_cert-mcp_certificates-mcp_missingcert/ so you might have to try that, but although I posted there yesterday, I haven't received a response yet.. though, other questions around it have been answered, suggesting that support for free learning path resources is not a priority.
