Object showing up in EXR render that is not showing in the scene

I’m trying to render a multilayer EXR sequence with Object Ids, but whenever I bring it into After Effects and view the cryptomatte, there is an object visible in the cryptomatte that isn’t showing up in the RGB layers or the viewport in Unreal. And I can’t find what object it is so I’m not able to turn it off.

I’m not sure it’s possible for anyone to tell me directly what’s causing this without viewing my project, but does anyone have tips for troubleshooting?

There is no Id where there is a fog tablet, if there is, you need to manually turn off a translucent selection
