Why does my HUD DrawTexture show borders on iPAD?

So I have a few buttons I’m drawing through the HUD (DrawTexture) function in Blueprint. When I run the game in the selected viewport or the mobile preview they show just fine. However, when I deploy and run on the iPAD I’m getting almost a dashed line around the borders of the texture as if for debugging purposes. I’m not sure why they are showing up and/or how I can get rid of them. Thoughts?

Thanks,
