Truncating of a system variable - ASM reference

We are currently experiencing an issue where the ASM reference for a block is being truncated.

The response page has the code: "supportid":"<%TS.request.ID()%>" and this has always given the full number, however now it is dropping the last digit. Is there some upper limit to the characters this can display? Can the ID's be reset?

Any help would be appreciated as it is making finding a reported issue more difficult.

Thanks in advance.
