P: Keyframe interpolation reverts to linear when changing effect values

In the newly released v26 - As title describes.

If you set a keyframe to anything other than linear - when inputting a value, the keyframe will revert to linear.

-except if a keyframe have separate interpolation choice (spatial / temporal)

I'm on stable release version "26.0 (Build 72)" cleary showcased the bug in the video and you can produce the same bug yourself quite easily. (The same bug also exist in 26.1 Beta as well.)

Thank you Ann and Dani! I had to double check what Ann said.. And yes, problem in happening on all keyframes that don't have separate spatial and temporal configuration

Hi @Daniel Lange, 

Thank you for reporting a problem. Issue can be reproduced and a bug has been filed.

As a workaround in the meantime (in addition to reselecting the keyframe interpolation), I was able to keep the selected interpolation by using the value graph in the Effects Control panel Timeline View or by making changes directly on the clip keyframe lines instead. 

Will update as we learn more. 

Sorry for the frustration, 
Dani
