Forge Grenade Glitch

Hey everyone.
Me and a friend have been building a forge map, and while almost everything is ready to go, there’s a glitch with two splinter grenades that can’t be selected or deleted. When you hover your cursor over it, there’s no option or anything to change location, settings, anything. I don’t know if this has been posted on here or not, but I just wanted to see if there was a way to fix it without deleting the entire map.
If you want to see the map on my file share, it’s called “Mayhem”. The grenades are close to the center of the map near the green side DMR. Thanks!
EDIT: Nevermind, I figured it out. Quoting TurbTastic: “Annoying bug, but usually is easy to fix. Create a new group of objects, ungroup them, and usually you can select the problematic objects again.”
