Tracking Learner Progress

I have created a simple module in Lectora Online. I have published as SCORM 1.2 for our Learning Management System. I have selected "The published course will prompt to restore the last viewed location within the LMS", however the learner has to continue to start over and the module is not opening up where the learner left off. I'm looking at every option to find out what is wrong and come up with nothing. Does anyone have any suggestions?
