I found yet another Naming Standards Issue
I'm trying to create both a unique constraint as well as a regular index via Unique Constraints and Indexes in Table Properties with the assumption it will use the Design Properties Templates. It doesn't.

As noted from the Template image above, my Unique Constraint template is {table}_{column}_UK
and my Index template is {table}_{column}_IDX. Yet, when I attempt to create the Unique Constraint, it creates the naming convention as CUSTOMER_ADDRESS__UK (2 underscores??) as noted below.

My assumption was that it needed a column so I added the column and also applied the Naming Rules - nothing.

Is my assumption incorrect about these Constraints being named via the templates? If not, what does Naming Rules do in this context?
The same behavior is evident when attempting to create Indexes.
I'm not getting any feedback on my posts. Are these bugs or just user error?
