The following technical issues have been resolved in GMGProofControl 22.214.171.124. Please note that the list describes the problem, not the solution.
Incorrect handling of Standard import for GMG Spot Color Control Strip
Standard data from ColorProof defining the target values and criteria for measuring the GMG Spot Color Control Strip was not imported correctly.
Measuring and validating the control strip with an external measurement device was therefore not possible. 
Missing Parameters in IT8
Some parameters have not been entered into an IT8 file created using the Export feature. The resulting file lacked information on the measurement device (type, serial number, illuminant, observer and measurement mode). 
Not printing labels automatically on measurement import
Importing measurements from an internal measurement device (eg. ILS30) did not trigger an automatic label print. [00955, UK-7738, UK-7023]
Wrong comment used during a manual validation
In some cases, the comment of an earlier measurement was used in a ProofControl Label and report.
