Those 1[.]A values are okay – they follow the SCORM standard. Lectora’s 1-A ones will be translated to this format when the course communicates with the LMS.
Not sure if this is the exact same issue I had, but I was experiencing some weird drag-and-drop-question reporting to the Grovo Delta LMS. I resolved this by deleting and re-adding the Assignable Unit (AU) at the top of the Lectora file and everything began to report correctly.
