Plane to sphere distorts titles and images

So I'm trying to edit in the new VR mode with a stereoscopic camera.

It works alright but when I try to add titles and images, they distort when I ad the plane to sphere option. Like the text follows the curve of the sphere.

I just want to add text and images that are straight when viewed in 3d. Like a title next to a person with titles and stuff like that. I want it to hover next to the person and be straight. Like a sign. As it it for me now, I get a curve on everything.

What am I doing wrong?
