Please, renew the function "Time Stretch"

It is not working since the previous version 10.0.5. Whe I select option “Audio->Processes->Time Stretch”, select event I want to modify, it is not possible to make any changes in editor, each attempt of modification the parameters terminates with result when editor makes its own changes and finally, after pressing the button “Apply” is nothing changed. Please repair this bug, it´s a shame. Thank you.
