Problem

Whenever you insert a new reference using the Citavi Word Add-In, an additional bibliography is created each time.

Causes

The Word Add-In fields in your document were converted to text in one of the following ways before you experienced this issue:

1. The Word document was saved in .odt or .rtf format.
2. The Word document was saved with Word for Mac or Google Docs at some point.
3. The Citavi command "Save a copy as static text" was used to convert the Word Add-In fields to text (see screenshot).
4. The Word command for converting all fields to text was used (shortcut Ctrl+Shift+F9).

Solutions

For causes 1 and 2:

Save the Word file in .docx format. Then, insert all references again.

For causes 3 and 4:

Open a recent backup of your Word document as described in this Citavi manual chapter.
