Solved Issues with tablet and mobile views on full width cycler

I have created a full width cycler and am using a background image on three slides.

I uploaded images for desktop, mobile and tablet.
Images sizes used are:
2400 x 740 pixels. (Desktop)
960 x 640 pixels. (Tablet)
500 x 550 pixels. (Mobile)

Desktop works fine but there are issues with tablet and mobile. Not sure if this is a limitation of the module or I need to make adjustments to settings or to my image sizes.

Tablet issues - profile view
slide 1 - image is cut off on the right slightly - note the text
slide 2 - OK
slide 3 - image is cut off on the right slightly - note the text

No issues with tablet landscape.

Mobile issues - profile view
slide 1 - image has padding at the top and the bottom
slide 2 - OK
slide 3 - image is cut off on the right slightly - note the text

Mobile issues - landscape view
slide 1 - image is cut off on the right slightly - note the text
slide 2 - OK
slide 3 - image is cut off on the right slightly - note the text
