Minor difference in the weapons bar and health HUD

[BakedBeanz77]

I noticed a while ago that my GMod HUD had a minor difference. The back graphic (like the yellow graphic on the health bar that flashes when you take damage) was off center. I couldn't find anything online at all. Can someone help?
