Verifying my recalibrated Jeti with my Klein, I have noted something strange: after one of my test sequences, CS appeared not displaying correctly Jeti measured data.
I see that the issue has to do with the "Probe Matching Active" flag and the "Active/Reference Probe" data. It appears when "Active/Reference Probe" data are set to None (spectro typical case), and, at the previous probe connection, the "Probe Matching Active" flag has been flagged (colorimeter typical case).

Quite easy to reproduce (also with different probes):
1. Connect probe1 and set it with no (none) probe Active/Reference data.
2. Disconnect it
3, Connect probe2 and set some probe Active/reference data and flag "Probe Matching Active"
4, Disconnect it
5. Connect again probe1
6. Try a few measurement in manual measure..... For sure you can note there is something wrong (see Figure 1 - I have measured 940, 320 and 64 levels)

PS: there is shortcut to fix: set some probe Active/reference data. Probe1 data appears as expected (see Figure 2). At this point if you flag and unflag "Probe Matching Active", the issue disappears.

Already logged as a Bug.
(But has nothing to do with any particular probe type.)
The issue is actually that the Probe Matching flag/setting is not disabled correctly when on of the Active/Reference probe options is set to NONE.

Thanks for verifying.
