Why does PTE 11 Pro sync music to slides even though I have unchecked the box in project options?

[Giusy]

I find in version 11 Pro several problems that I didn't have with version 10, and it really complicates my work, I don't know if anyone else has noticed this or if it only happens to me because I make long audiovisuals, on average they are over 40 minutes and therefore it really takes me much longer because even if I save the work when I reopen the project I find that PTE has made changes.
For example, in the project option for music I deactivated the "sync music to slides" box, because I prefer to adapt the music manually in my audiovisuals that are made up of photos and video clips. Unfortunately it seems that PTE does not respect my choice in fact it always changes the timing of the slides especially in those positioned before a video, (for example a photo before a video is on 7 seconds and the video on 25 seconds, I save and when I reopen the project to continue working the photo is on 25 and the video on 7 i.e. inverted and I really do not understand why, so every time I have to check and change the timing again before being able to finish and publish, also generally the slides go from 5 seconds to 7, while PTE changes them some are 3 seconds others 9, it is really frustrating.
Furthermore I also noticed several problems with the preview, the music is not synchronized as when I watch the video from the timeline, and this is a big problem.
I hope you can understand my post because I do not speak English and I used google translate.

I have not had any of these problems that you describe.
There is no difference between V10 & V11 that would cause this.

Even if you wish to adjust the music manually you still need to keep the 'Sync Music to Slides' ticked, so that it will play correctly with the Slides.

I do not understand how the timings can change when you save the show & reopen it.

Make sure you are using the latest version  11
& also untick 'Full Duration' as this can cause problems if you move Slides to different position or even adjust the timings.
