LMSSetValue - How to remove it?

I am working with a vendor to upload two Captivate courses. The vendor handles all the uploading and connecting of things - I just hand them a zip file, so I know very little about their process. The two modules are apparently jumping directly to the "thanks for watching" slide at the end. I cannot replicate it on my own system here, so I don't know what's happening. The vendor sent the notice below and I have no idea how to fix it. I don't know how they found the error. My opening slide has no "on enter" actions and only has a button to go to the next slide.

From the vendor:

After some further investigation, our Technical Team has advised me that the issue with these courses is the following value causing the course to be marked as completed immediately: LMSSetValue cmi.core.lesson_status, ‘completed’. If you could please correct this, and re-upload these courses, we would be glad to update the site. Thank you! 

Can someone guide me to where I might address that LMSSetValue?

Thanks!
