Fit 'Contain' and 'Cover' not working?

Hi All,

I’m having an Issue where the images are selected to ‘cover’ (under fit) and it works fine but after a while it doesn’t work anymore (doesn’t fill the image box). I click the fit to contain (so not cover) and seems to work for a bit, but then fit=‘contain’ stops working too, then I do the opposite click contain back to fit=‘cover’ and works. A vicious circle. How do I get it to work and stay working.

Please help
Anton
