Database 'views' acting erratically

Anyone else have a database view that acts erratically?

My views constantly re-order and stretch themselves. Some things disappear and new things appear in their place.

As an example, here is a view called ‘Models’ - it is showing a blank column and ‘First name’ is missing even though I’ve check boxed it in views. The profile image column is showing text.

Happens all the time.

But why?
