Bug in crop tool

If for the crop I select ‘manual’ and then I switch between different aspect ratios, the aspect ratios are not respected.

For example if my original image has an aspect ratio of 3:2. When I then switch to 1:1, it will show me a square image. But if I switch back to ‘Original ’ aspect ratio, the image remains square! If I then click on the crop tool to visualize the crop grid, it seems that the grid starts outside of the image frame, but the visible area is neither 3:2 nor 1:1, so something weird is going on.

I’m on a Mac, with PL9 trial.
