In software version 2.5.0 and earlier, ColorSource cannot record color values set using direct emitter controls via the ColorMix tab to color chips. This issue was fixed in ColorSource console software 2.6.0, which is in open beta as of Feburary 2019. Information on the ColorSource 2.6.0 beta can be found here.
Steps to Solution
If updating your console is not possible, you can work around this issue by setting your color via the color picker, then recording the color chip.
