Preserving Audio/Animation Timing When Importing Presenter '13 into SL2

Hi there,

I am working with some very old presenter '13 files, and hope to convert them as seamlessly as possible into SL2.

However, I notice that when I import into SL2, the timing on the objects animations (such as fly-in, etc) become de-synced from their original audio timing. 

Is there any way to preserve the timing elements set up in Presenter '13 when importing into Storyline 2? Or must I recreate all of the timing from scratch?

I have many courses to translate from Presenter --> Storyline, and trying to gauge how much man power this might take.

Thank you!
