Reflection Capture Issues

We are working on a small arch-viz interior scene and are having issues with reflection captures. We have a fabric material with roughness set to 1. It is displaying correctly until we add a box reflection capture to the scene. Once we added the capture the material begins to look reflective. See images below:

We fixed the issue by making the fabric materials specular values 0. If you have nothing plugged into specular its default is .5 therefore some reflection is possible. Just a heads up for others with this issue.
