I have "Hide objects on base layer" and "Hide other layers" checked on the slide layer properties. I have also ensured that the base layer items are unchecked on each layer's timeline. When I preview the module, it works perfectly.
However, when I publish the file to AICC (works with our LMS), the base layer is showing. I've also published the file for LMS and then selected "VIEW PROJECT" (not in the LMS) and the base layer is showing on the slide layers.
