I am having a similar problem exporting a Text Preset. When I am creating it, there is a horizontal line that cuts it off and I can't move it so the whole letter is inside the area. I had to make an image of the Signature to be able to have it complete, but I would like to be able to use the Text option which has such a nice drop shadow. I am using Lightroom Classic and Photoshop CC with last updates. Thank you very much!
