Just an observation - Ver. 26.1.4 - When i mouse hover over any alias in the new rules, the value (contents) no longer shown. I get the value of Description or Type fields instead.
added an image - the alias shows "type" Networks, when hovering, instead of RFC-1918 values.
I noticed this prior to today's update also.
We found the issue, thanks for the report.

Sorry, I missed this earlier and restructured the code a bit so the error is less likely to happen in the future:
