Relative Item wrapping when I don't want it to

So I'm trying to make a diagonal pattern. So far I have this.

But I want to fill in the gaps, so I figured I would use relative item to connect the points in the voids into a polyline.

When I connect {0;0} (0) to {-1;0}(3) it produces this

Which is good, but then when I try to do {0;0}(0) to {+1;0}(1) it does this!

I have the wrap paths and item on false, so I don't know what it is wrapping backwards!

Here is my definition

Can anyone let me know what I'm doing wrong? Is there a better way of creating a diamond pattern than what I'm doing?

Thank you!

So I got a little farther! I got two edges of my diamond to work, but the last two are giving me troubles.

As you can see from the picture, one of my line components won't work unless I use another list item component? Maybe this is a glitch? Shouldn't all the list item, index 0 coming out from item A be the same if the tree is the same?

Also my last line is wacky. Preview it to see for yourself! I don't know why it doesn't work.
