1. Military Symbol Editor includes additional attributes beyond just the attributes for the labels displayed for a particular symbol. This issue is a known limitation or as designed. It displays all the attributes for the feature class so they can be set. For example, Unique Designation must be set despite this label not displaying for a given symbol.
2. Planning symbols are missing dashes. This issue was resolved in several previous releases.
3. The Unique Designation label is missing. This issue is resolved.
