If you connect your spectroradiometer to CalMAN first, And then connect your colorimeter, then create profile, you will not have this issue. We will update you guys as soon as we know more on when we will be releasing a fix.
Thanks for investigating this.
It isn't related to just the spectro, I have an i1pro2 and this never happens with a Discus.
It could be related to using a spectro and a colorimeter both made by xrite, which is the most common brand for enthusiasts / non pro users.
Shoman94 reported having the issue with a Colormunki, not an i1pro2, and an xrite colorimeter (forgot which).
Try an i1pro2 with a non x-rite meter, you shouldn't be able to reproduce the issue.
For those wondering how many professional calibrations are affected by this, the answer is zero.
Only an amateur would re-use a profile made with a different display in a different session. A pro would always run a new profile for each display/projector calibrated, and a pro would most likely not use an x-rite spectro anyway, which isn't a reference meter. A pro would also verify some of the calibration with the spectro, to make sure the results are valid.
Only amateurs do not run a fresh profile for each session when they want accurate results, and do not do a final check of the results with the spectro.
Not to say that this bug shouldn't be fixed, only that it doesn't happen with every meter combo and most likely doesn't happen for a professional calibration, because both the method and the meters used would be different.
