Problem with Number Generator

Hi everyone,
I created a FCPX title in Motion including a number generator formatted as a currency to visualize rise of total costs.
Before and after the generator, I crated a normal textfield to show previous and the current costs.
In the FCPX preview everything looks right, but in the exported video the value is rising slower and doesn't stop when it should.
Can anyone help me?

(working in FCPX)
(not working exported)

Did you make sure your motion project frame-rate matched your FCPX project frame-rate, and your FCPX projects frame-rate matched your export frame rate?

I've found for time sensitive things (countdown leader, etc...) It can be easier to export a pro-res video from motion and use that in FCPX.

Hope this helps,
Mark
