Hidden playbar issues

Hello, I have an E-Learning module I'm working on that is throwing up some issues. The module will be viewed via Moodle on our College network. I have set the skin editor up to hide the playbar on knowledge check/quiz questions, and I have 2 drag and drop questions, and 4 multiple choice questions. The drag and drop were set up on a blank slide, and the multiple choice questions were set up on the default 'knowledge check slide'. When I have uploaded the project, the playhead is hidden on the drag and drop questions, but not on the multiple choice?

There are a few instances within the module that the user can go back and forth on some slides. for example, a slide set up with 4 menu options and the user can choose which one they want, instead of viewing them sequentially. I've advised against this but this is what has been requested. Would this be what is causing the problem? It works fine in the project preview within Captivate.
