I have the following tex document where I have two tikz pictures and they clash.
The current version of the document works for a single tikz picture but when I try to load in another tikz picture I get a weird result.
That is, running the document below should give the correct output (as below - along with another plot).
However if I comment out \iffalse on line 46 and then \fi on line 162 I obtain a different original picture.
What I want (along with having both plots in the same document and not just this single plot):
What I get after leaving \iffalse and \fi section commented out:
The first tikz is unaffected and its just the tree tikz that is affected and I cannot seem where the two pictures clash.
