Remove Timestamp from Coursepress Certificate COMPLETION_DATE

Apologies if this has been answered before - I am seeing that Coursepress takes date format from Wordpress general settings, but this doesn't seem to be working for me, and there's a second issue.

When I preview the certificate in course settings, it shows how I want it to: "March 1, 2017"

However, when the certificates are printed, COMPLETION_DATE is printing "2017-03-01 15:21:27"

Firstly, it seems to be a bug that COMPLETION_DATE is not taking the format "March 1, 2017" from my Wordpress settings. Second of all, I'd like to remove the timestamp "15:21:27" entirely. I'm not sure if this is a related issue.
