Issue
In a Niagara R2 station, a folder with a very high number of links shows completed link tags as “??” instead of the usual alphabetical letters.
Product Line

Niagara R2
Cause
Niagara R2 uses alphabetical tags for completed links starting from a to z, then aa through zz. When the number of links exceeds this range, the system displays “??” as a placeholder.
This is a display-only limitation and does not affect system performance.

Resolution
- No corrective action is required.
- The “??” tags indicate that the tag naming sequence has been exhausted.
- System functionality and performance remain unaffected.
