Trouble getting good results with knuckle Probe

Good afternoon everyone, I am currently trying to measure features on a tubed part. I have a 5 way that i am using but only using two tips. I thought my knuckle was working for a little bit and I use my master to calibrate both directions and then switch to my probe build and calibrate all tip 1 angles first then change to Y+ direction for the knuckle calibration and i thought the StdDev looked ok but everytime i try to measure the features at the bottom, it is giving me Very High Results. I measured the same part a month ago and all the features were in spec underneath and now i am measuring the same part and all the features say they are way out. I am totally confused by this and I've exhausted all options. Can someone please help? Attached are images of my probe build and setup.
