Corner Cabinet Counter Top Extends Through 45 Degree Wall?

[HumbleChief]

Tried this a few different ways but as soon as I join these corner cabinets the counter top extends through the corner. Can't figure out how to cut the counter top.

 

Thanks

Tried it as the first thing (of course) but every time I joined the cabs, even with no counter tops that piece would extend beyond the corner.

With no counter tops, as soon as the cabs are joined that piece extends past the corner - IN 2D. And of course now a custom counter top works perfectly. Still get a weird 2D piece that remains but 3D looks good.

 

Here's the 2D view.

 

 

 

And here's, same cabs, the 3D view. Just a little confusing but am over it.

One to report I'd say if Auto Fillers aren't finding the angled Wall.
