Instanced Static Mesh Translucency Too Translucent

I have two meshes. One is a destructible and one is a HISM instance. I turn the destructible on when the player is close enough to interact with it and I turn it off when the player is far enough. The HISM instance does the opposite.

My problem is that there is a clear (no pun intended) difference between the two in regards to translucency. It seems like the HISM instance isn’t getting the same kind of love from the renderer as the destructible.

This is the destructible

The HISM instance is too transparent. They even let me see other translucent objects that are very far, and they disappear when I move to a position where they are no longer overlapping on the screen.

I would appreciate any help because this is a bit of a show-stopper and I’d have to deal without the HISM performance gain.

Thanks!
