Transmission case

[Dhos1]

I brought a case and I was prepping it for paint, but o saw this…looks like it was grounded down or cut off in the corner. All holes are still intact. Are there any issues with this or can it be smoothed out and not affect anything. It is on the feet side right below a bolt hole
