Builtin functions have two column entries in graphviz

Summary

When looking at graphviz images for a cached query that has a builtin function, the project_reorder node has two entries for the builtin function. I see this in the pre-mir, post-mir, and dataflow gaphviz images. I'm not sure if this is an actual bug, but it's unexpected behavior (to me, at least)

Here are several graphviz from queries with different builtins, each builtin has a different numbers of input parameters (the color image is a dataflow graphviz, the others are pre-mir):
