I have created a .psd file with a background layer that I added a stroke to. Adding the stroke worked fine until I had to re-size my canvas. After I re-sized the canvas my stroke now only appears on three sides of my layer. I have tried to edit the stroke, even tried to delete it from my layer but I cannot get anything to work.
Why did my stroke drop from one side of the layer after I re-sized the canvas? How do I fix this? I am running Adobe Photoshop CC 2015.
