Multiple fileds with SIGN SEAL flag created when append RTF to another RTF

Hi, I have a problem with RTF’s.

I do the following:

Set item1 = doc.GetFirstItem(“ItemName”)

Call item1.AppendRTItem(item2)

Call doc.Save(True, False)

Then I have three filds with the name “ItemName”.

There are not exact copies, and one of this have the flag SIGN SEAL.

Compact and/or update not help.

Thanks.
