My medical was also updated after 1 month when I send a message to IRCC.
It Gckey qccount, at the bottom you see "Report a problem or mistake on this page".
Follow this link and in message you can mention the date of medical you have performed and the date you received email from Panelist about submission of results to eMedical.

After I sent this, I received a reply from IRCC that they have forwarded my inquiry to relevant visa office. They also informed me the name of visa office where my application is processed and asked me to contact visa office directly for future corresponding. I hope this may work for you.
