This is sounding more and more like academic work for which you earned a certificate. Where I'm from, a certificate is 75 hours of instruction. It does not sound like continuing education credit which is an hour here and there to maintain credentialing.
Better to slow down your application by a couple weeks than to sign off on an application that is found to be incorrect. If someone who knows of these type of programs sees that you didn't list it within your coursework section of the application, it could hurt you.
Were the courses pass/fail or do you expect to take a GPA hit if the courses are included?
