Coordinates error in the Pyxel Editor
When using the Pyxel editor, installed on an M1 device, the standalone version has a couple of errors. Copying and pasting is not working, as it tries to copy from one coordinate, near the start of the image bank. This problem is related to the second problem, which is that the coordinates shown on the image bank are not multiplied by 8 when moved to another position that is not the start. For example, when moving down with the arrows, the coordinates are 0, 1 instead of 0, 8 (the upper left corner) 

Attached are 3 images of the problem
