D1 Pro 40W Mirrored Text

I have an xTool D1 pro 40W and have found that text prints as a mirror image even when doing a material test. When I first had the software and before I told the software about my bed size I was able to print text and material tests with the correct orientation. So I assume I have changed something but have been unable to fix the problem. Can you help? By the way when using the xTool Creative Space software text prints correctly so there is nothing wrong with my laser.
