The following merit badges print with a generic merit badge image instead of the proper image:
Archery - generic
First Aid - generic
Canoeing - generic
Emergency Preparedness - generic
Camping - generic
A number of these display the correct image for the (OLD) version, my guess is when the merit badges were updated the images were not properly assigned to the new version of the merit badge definitions.
They seem to be the ones that were updated to new versions recently.
