To answer your question about the bundle:
The "bundle" item is just a notification that you registered for the bundle. There are only two modules in the ACMA 5 to 6.1 bundle.
When registering for the ACMP 5 to 6.1, you must only select the courses you have not already registered for. In this example, because you have already registered for the Licensing and Visual RF modules (part of the ACMA 5 to 6.1), you only need to register for MAS, Security, and Spectrum Analysis.
Please note: Because we do not allow duplicate module registrations, if you attempt to add a module that has already been registered, you will not be able to proceed with registration. You must remove any items from your checkout cart that you have already registered for.
Hope this helps!
