Image rotation?

So i’ve been using imageJ for years, and previously had no issues when an image was open, going to rotate it a designated amount which input.
I recently updated my Mac OS, and had to update the image J application - now when i go to rotate the image, i can do the “rotate 90o”, but when i click on rotate and want to choose the rotation amount, its fixed at 15o. When i try and type in a different value, nothing happens. Its like the keyboard isnt working (but if it wasnt then i wouldnt be able to type this question!). Anyone had this or know how to fix it? is it a “bug”.
