Using more than 1 Planar reflection capture in a scene - Multiple captures won't work

I have a scene, where I have a building with a sliding glass door in the shape of an L that sits in the corner of the building. I dragged in 2 planar reflection captures for each side of the glass door but only one reflection capture will render at a time while the other one just doesnt seem to work at all. If I hide the first one the second one becomes active. Not sure what im missing and why this is happening.
