Feeback Layers Crashed

Hi,

I'm creating a course that includes several graded questions. In the last week or so, I've been back and forth with support because the feedback layers are so wonky. The feedback boxes are left aligned, the buttons are overlapping the text, etc, and the layout will shift from slide to slide. Support told me the file was corrupted and the issue remained even when they tried importing it into a new project. 

I would like to move on with my project, but I'd love feedback on my options.  Do I need to start this whole course over, or should I delete all my graded questions? I feel like I'm lost on this one.. this is my first poisoned file (sad face).
