quadrant(T) suffix returns original image

[tumispro]

URL's appended with -quadrant(T) (i.e. https://www.example.com/image-240x240-quadrant(T).jpg) return the original image, while appending -quadrant without options (i.e. https://www.example.com/image-240x240-quadrant.jpg) returns the T quadrant center cropped version. Both files are created on the server. Am I missing something?

Correction: appending quadrant (without T option) seems to just return the crop, not the T quadrant. So the quadrant doesn't seem to do anything at all, except that specifying the T also doesn't crop it at all.
