Looks like it is a bumpmap effect to me 
Bumpmap has beveled the pattern edges. You can perform a fix as:
Use Layer -> Transform -> Offset then click by width/2, height/2 which puts the edges in the center. https://i.imgur.com/IrRawd0.jpg
Now do an 'artistic' repair, various ways, I used the clone tool for this, your project, spend some time on it. https://i.imgur.com/gynUMdC.jpg
When finished, repeat the Layer -> Transform -> Offset by width/2, height/2 to swap the fixed center back to edges. Gives a tiled pattern like this: https://i.imgur.com/LIdh8PY.jpg
