In the new version (26) the transform effect keyframes reset when adjusting values

When using the Transform effect in Premiere Pro 26.0, adjusting the scale or position values causes the keyframe graph to reset to the default interpolation. Previously customized easing curves are lost, and I must manually recreate the graph each time.

Issue:
Transform effect keyframe interpolation resets when adjusting keyframe values.(IT HAPPENS TO EVERY SINGLE PROJECT IN THE NEW 26 VERSION, BOTH ON MY WINDOWS 11 AND ALSO ON MY MACBOOK M4)

Steps to Reproduce:
1. Apply the Transform effect to a clip
2. Add two scale keyframes
3. Adjust the interpolation graph (ease in/out)
4. Modify the scale value on a keyframe

Result:
The interpolation graph resets to default and removes the custom curve.

Expected Result:
Adjusting keyframe values should preserve the existing interpolation.

Additional Issue:
Because the graph resets automatically, creating and using Transform presets is currently impossible.

This behavior did not occur in Premiere Pro 25.5.
