Corner Door Pocket Double Sliders?

[rob2218]

well, ok, I have a corner sliding pocket door condition. I'm getting this "sliver" of a piece of material that occurs in the corner.
The walls that meet the corner are made up of 4 walls. 2 walls (running top to bottom of the image) create the "shell" if you will. The sliding "pocket" double door which runs N-S on the image is being hosted by a wall that the ends have been brought inward to create effect of a pocket sliding door.

The remaining wall (running E-W) is made up of one composite wall. There is a single pocket door in this wall.

They must meet at the corners but I'm getting this odd "sliver" of material (see 3d).

1) How can I adjust the "gap" for a pocket door? Seems there is no variable to do this?
2) How can I get a WIDE gap and how/where can I find a double pocket sliding door?

thanks.
