The module name defaults to "Captivate E-learning course" when it is posted to the LMS. The project title, project information, and table of contents are named properly in Captivate with the real course name. Is there another place in the Captivate 8 software where the LMS might be drawing this default name from? I have to rename the module whenever it is posted to the LMS.
I'm assuming you're publishing as a SCORM project (or maybe Tin Can). If you looking at the quiz settings, under "Reporting," you'll see a button called "Configure" near the top, next to your chosen standard (like SCORM 1.2). Click it, and you'll see where that annoying "Captivate E-Learning Course" title is coming from. Edit it to whatever you want, save the project with the new settings, and you should be good to go every time you publish in the future.
