How to correct a corrupted ID of a reported item

I have a page for tracking issues related to a specific software tool. Each new topic is called Item1, ... Item53. Normally eacht item is listed in the Tracking WEB with an ID, for example, Item49 (linked to http://foswiki/Tracking/ThisTool/Item49).

One of the items displays on table of section All bugs which are new or being worked on as ID, instead of Item53, the following long text:

(quote start)

RossmannSubject: ToolName 5.3.1.6 Dear Mr. Rossmann Wir haben kürzlich entdeckt, dass das ...">Item53

(quote end)

Btw, this text is part of Item53's description...

We do not know how this happend - all other topics worked fine. My guess is that when cut-and-pasting the content of an E-mail in the Desciption input-box, in the text:

... from: A. Rossmann<newline>Subject: Dear Mr.  Rossmann ...

the newline disappeared and a WikiWord resulted, something like ... from: RossmannSubject : Dear Mr. Rossmann. That might have mixed up BugsContrib...

This is also not a severe problem, but I would like to correct the text and link of the Items ID. Unfortunately I could not find out how. Can you please help me?

In case that is not possible, can I solve it by copying this Item (using More Topic Actions -> Copy Topic and naming it Item54 or so) and then delete Item53 (with More Topic Actions -> Rename/delete Topic)?

Many thanks
