JIT Spacetree Node Spacing Issue - spacing

Question

I've having an issue with JIT Spacetree where the nodes are being space massively far apart resulting in an unusable view. The first few nodes are fine but as you navigate deeper into the tree the spacing on the child nodes increases.
I'm using a pretty vanilla config very similar to example 1 on the JIT site
http://philogb.github.io/jit/static/v20/Jit/Examples/Spacetree/example1.html
Here's a screenshot that show a snippet but the problem is even worse than this shows as the spacing increases even further with additional nodes.

I've used this successfully for a while but never come across this particular issue.
Has anyone any ideas / thoughts?
Thanks

This may not be the cause of your issue, but you have duplicate nodes in your json structure. Id's must be unique with SpaceTrees in JIT
