Hey, strange stuff happens for the first time:
- LR4, LRT4.5.1:

Editing keyframes - refreshing - calculating - saving: works so far
After reloading the metadata in LR the temp, tone and clarity is completly wrong, even in the edited keyframes... see before after in the attached screenshots...

Thanks and BR Johannes

First approach would be to redo the workflow. Start by completely resetting all edits (right mouse on folder in LRT, then "Delete all LRT editing").

Then try again and carefully check the curves and values in the table in LRT, do you see any anomalies after applying the transition in LRT?
I don't think there is a bug involved here.

thanks now everything's fine!!! Regards Johannes
