I've noticed that when I use my i1 Pro3 in the Configure Matching menu, the naming convention I use does not always activate the Probe Matching swatch sequence. For example:

I've used the following naming convention:
2_SPECTRO_ClientName_MonitorName_YYYYMMDD

When I go to — Configure Matching > New — and type in this naming convention, it's usually a 50-50 chance that it will activate the color patch sequence. Most of the time ColourSpace freezes up altogether.

As a means of troubleshooting, I've simply typed in the word "test" instead. This works!

I've attempted to swap the underscores with dashes, such as
2-SPECTRO-ClientName-MonitorName-YYYYMMDD

Most of the time, this works as well! But not always.
At this point, I feel that my naming convention may be too long — especially if typing in "test" seems to solve this issue.

Is this a bug I'm experiencing? I'm currently running Version 1.0.0.2146.
Or are there limitations that I should consider when using the naming convention I mentioned above?

Please let me know if you require further clarification. Thanks in advance!

Unable to replicate.
But I've not tested with an i1Pro3, so that may be your issue?
Try using a different probe.

If not that, you will need to provide more information on your actual workflow, or make a video of the issue using a screen recording program using something like https://screenpal.com.
