XGP issue

[smaurice101]

Hi , thanks for creating XGP. I am seeing strange results when Predicting. Here is my GPConfig:
{"LossMetric":"mse","EvalMetric":null,"ParsimonyCoeff":0.000011287758833851027,"PolishBest":true,"Funcs":"add,sub,mul,div","ConstMin":-3.386327650155308,"ConstMax":6.772655300310616,"PConst":0.05046614361039843,"PFull":0.05046614361039843,"PLeaf":0.033194777090305556,"MinHeight":2,"MaxHeight":5,"NPopulations":1,"NIndividuals":21,"NGenerations":17,"PHoistMutation":0.069682804147633,"PSubtreeMutation":0.069682804147633,"PPointMutation":0.069682804147633,"PointMutationRate":0.014094429989179022,"PSubtreeCrossover":0.02132923112731088,"RNG":null}

Here is the data: YPRED is the prediction (they are all the SAME) and the values in bracket are the X column values (8 columns in training dataset):
