Effects programmed in Effects Control panel are not showing when played back
I am zooming an image from0 to full screen. I select Scale and then make my adjustments and add keyframes. Up until now I could see the effect as I moved the playhead. Now nothing is happening. I amusing PP 2019. MacOS 10.12.6
It was working fine then I opened the project today to continue work and when I went to zoom up an image via Effects Control panel it does not show what I programmed. I select Scale in the panel. I set the scale to 0 and place a keyframe. I then set the scale to a larger size and set a key frame. I was able to see the effect and make adjustments. Now the image is unaffected.
