Sorry you're having this problem. We'd need some real details about your projects ans system to have a chance of helping you, but up front I'll ask if this is happening while you're using the Batch Produce feature.
There is a known bug where ALL audio tracks are enabled when projects are produced using Batch Produce mode.
If this is happening when producing the projects individually, a possible workaround would be to produce to an ISO file or to a folder first so you can preview the results before buring a disc.
If you'd like more assistance, please read the Read Me Before Posting thread at the top of the PD17 forum index page and attach the DxDiag results along with the exact version of PD17 you have running. It would also greatly help if you could provide a screenshot of your timeline, and even better would be to pack the project and upload it to OneDrive or Google Drive and paste the link here for others to test it out.
