Why are model tags duplicate ?

[seanccc]

Hi ,

I always have a question although it's not so important.  For every term of the mode tag , I see duplicate tags .  but why ?

If you don't mind, please report this as a bug on support.ptc.com, I don't think I've seen that behavior before.

Also verify in the actual tag library that there aren't any duplicates or special characters in the tags, like EventParameter#1, EventParameter#2 ...
