What could cause my glasses to come out of my near-new dishwasher like this?

Hi all, I bought a new Bosch 3 series dishwasher last year and I'm finding it's not really cleaning the glasses well. I've cleaned the filter but it hasn't made a difference.

What could be causing this please? My wife insists on using a natural dishwashing powder but I doubt that's the issue? Any guidance would be super helpful!
