Audio doesn't migrate together to new project

Hi guys

I just decided to migrate my offline edit timeline to a new project to continue my color grading, the reason why I migrate my timeline is staying at the current project is too heavy. There are a lot of footages & other stuff in it.

So after copying my timeline to the new project via Dynamic Project Switching, I realise my Synchronised audio wasn't migrating together with the other materials.

I'm now currently on Davinci Resolve 15 beta 6, MacPro Late 2013.

I'm unfamiliar with Dynamic Project Switching, but I was recently successful using a simple Copy/Paste from a timeline in one project to a timeline in a new project.

Yeap I actually copy/paste my timeline when I'm in dynamic project switching mode. Everything works well beside the synchronized audio, which is very weird.

My own synced audio came in fine with the copy/paste.
