Hi there Jaun Claude,
we are still on the latest 12.5 but I verified the same behaviour in the latest 14. Tested on OSX. I'm afraid I can't give you exact version numbers atm as I'm not at work anymore.
I just tested at home with v15.0.0B.057 on Windows 10 Pro, same behaviour.
Each time Studio version, of course

I know these details are important, sorry for forgetting them earlier. As it exacly exports the in/out points from the timeline, ignoring the travel of the curve, I have a feeling that it's "intended" behaviour :/
