Cropping and image Generative Expand

I use to be able to open an image.

Then crop to where the edges would go wider and taller than the image.

So there would be a white space all around the image.

Ok, use to be white, now it's all squares ???

Then I would click a botton on the bottom of the page and hit generative expand or fill but it doesn't work any more. If if I type in a word or sentance of what I want it doesn't work.

Any ideas how to get that back or reset it ?

And how do I get rid of the squares and go to just a white area when cropping larger ?

Hope I explained all this right.

Thanks for any help.
