Can't ease in/out shape path

[mcneillm]

I'm fairly new to Premiere Pro and I'm trying to change the temporal interpolation of the keyframes for a shape's path. When i select the keyframes and right click, I can see the options to change to but they are grayed out and cannot be clicked. Also, Linear is already checked but like I said I cannot change off of it. All help is greatly appreciated!

You cannot change the interpolation for mask keyframes.

Thank you for the quick response! Is there any workaround or other method I could use to achieve the same thing?

In Premiere not that I know of.

Alternative is to use Ae.

How have over 3 years past and I still can't change the interpolation for mask keyframes. I don't understand why not?..
