Stereoscopic 360 Black Lines Error

Hello, I’m struggling with the stereoscopic plugin.
I have followed everything from the official guides and I have also looked at the post of the Ninja Theory (Capturing Stereoscopic 360 Screenshots and Movies from Unreal Engine 4 - Unreal Engine) but I cannot solve my issue. I Have black lines in the final images and I don’t know how to get rid of them.
Anyone has a solution?

Thank you for your time.
