I am trying to move an image from the right side to the left side. By setting the start position, I can set the image just outside of the right border. Then I do a left movement and the image starts coming in from the right side. However, the movement stops as soon as the left side of the image hits the left border. I want it to disappear by going past the left border. So I tried to adjust the end position. However, everything is grayed out. See attachment. I couldn't find anything in the documentation that says why this might be grayed out.
