I have some trouble with the rotate function (via Studio/transform). If I duplicate the layer I want to rotate, then choose the Move-button and then the transform function I have either the problem that -90° is shown instead of 0° so that the picture will rotate by 90° per step, or, what is worse, if I duplicate the last layer, which has - luckily - been rotated by 6°, the duplicated layer does not rotate any more. If I look into the transformation function of this layer, it shows 6 ° but nothing happens. What is the problem?? Thank you for your help.
