Weird performance on right align,

Hello Ari,

Thanks for sharing your project file with us!

The reason why your image is not aligning close to the rightmost section of the slide is because Storyline 360 is allotting enough space in the slide for the states of the image to display properly. Here's a screenshot of what your image looks like when aligned to the right:

And here's what it would look like when the state of the image is changed to something else: 

You'll notice that the rightmost section of the image is lined up with the edge of the slide. If you prefer to have the main image closer to the right, you'll need to move this image manually. Take note that this might cause the states of the image to get cut off when shown on screen. 

Hope this helps!
