Trouble with algo.pagerank()

I am trying to create a page rank for my FIELD nodes based on the number of MODIFIES relationships they have. I am using the guide to create my call
CALL algo.pageRank("FIELD", "MODIFIES", {iterations:5, dampingFactor:0.85, weightProperty: null, write: true, writeProperty:'pagerank', concurrency:4}) YIELD nodes, iterations, loadMillis, computeMillis, writeMillis, dampingFactor, write, writeProperty

But all of the pagerank properties are the same, even though it I have many fields that have multiple MODIFIES relationships with FIELD nodes.

What could I be doing wrong for my rank to come back the same for every node?
