Issues with alignment

I think what happened is you took the arrows in the diagram as meaning the same as the arrows on the bushings.
A visual check can verify this.
On the front side of the A arms the offset hole in the bushing should be toward the engine, and the holes in the rear of the A arm should be away from the engine.

This is the only thing I can imagine happened because I was able to get +3 caster on both wheels easy.

Toe in would be about 1/8 with rubber lower control arm and strut bushings, and 1/16 with poly lower control arm and strut bushings.
