Issue
In a Niagara R2 station, a particular folder has a very high number of links. The completed links in this folder show tags with "??" instead of the usual letters.
Environment
Niagara R2
Cause
The "??" tag names indicate that the available letter tags have all been used up.
Resolution
They start at "a" and go to "z" then re-start with "aa" and finish at "zz". If there are additional links, the tags display "??". This is a display only limitation and will not cause any performance issues.
