Selection Criteria based on certain properties are case sensitive. Try matching the case as it appears in the error message. Custom.TermType
Sorry, a little background:
Someone else setup the properties spelling them a certain way many years ago (These properties are apparently case-sensitive).
The RF devices, of which there are about 900 total sub-divided into smaller groups, have 'TermType' spelled lowercase, or in other groups, partial case (Termtype). When I try to add a new package, it wants me to save the group properties with upper-case 'T's. If I do that then the 80 devices in that group will also need to be changed, individually. All I want to do is add a package without being notified that the spelling on a pre-existing property isn't cased properly, and refusing to let me save until corrected.
Thank you for the additional information Steve. Could you let us know what version of Avalanche Server you are running?
This was a defect and should be corrected if you update to Avalanche 5.3.
