ios Mobile checkbox border bug

I have a custom checkbox and a weird border appears around my checkbox SVGs. On the website web app, tablet, and Andriod devices it doesn't appear. Only on IOS, Has anyone come across this before and know of a fix. I have spend days looking for a fix, doing CSS hacks, googling and working with other dev's on the team and trying to find a way to inspect on mobile, but to my knowledge, not a possible thing to do on a mobile browser. Attached is the image.
