Camera Getting Switched to Perspective Mode At Runtime

Hey all, not sure if this is the right place to post this. I'm having an issue with an additional camera in my oculus VR project. The camera is meant to be orthographic where its view get's rendered to a render texture that I use in a shader.

I'm able to get the camera displaying how I want when not in the play mode, but my problem is that whenever I run the game, the camera seems to switch to a perspective mode. It still says orthographic in the inspector, but this gizmo (and ultimate result) is clearly no longer orthographic.

Has anyone else encountered this?
