Slur and acciaccatura in chords

[Stephen MacNeil]

Hello all! Up until now I have never really dealt with  chords using slurs and acciaccatura. I can't seem to get it to goto the proper note easily. When I do there is little to no consistency between how it looks in reference to the rest of the score. ie. it looks like I had to alter it.

Any help would be great. Below are some things I have been trying. Also I know that I can change the slur to direction however, I would need the directions to stay as they are. Since this is how "traditional guitar music is written"   (slur goes opposite stem direction).

Thanks
