Problem with calibrating 2017 LG OLED

[cabrider]

I am experiencing a strange problem using HCFR to calibrate my 2017 LG OLED TV. I last did it 2 years ago and decided to recheck it today. The problem I have is that using the same settings in HCFR and on the TV as last time I am finding it impossible to make any sense of the grayscale readings I am getting. A sweep with the current settings was way, way off, so I reset it and tried again but the result that using Warm1 setting showed green slightly low but red and blue where both off the scale, red high, blue low. I've never had readings like this before and checked my laptop and another TV which came out fine so my Spyder5 is ok! Does anyone have a suggestion for what might be the problem here?

I think I've found the problem. The selection of the display type as WRGB OLED 2017 B7! There is obviously something wrong with this setting as changing to the 2016 B6 setting gets rid of the problem. I have no idea why because I've used it before with no problem.
