Common issues with EndNote

Sync conflicts

Sometimes, when multiple users or devices edit the same reference in a shared or synced EndNote library, a sync conflict can occur where EndNote doesn’t know which version of the reference to keep.

To resolve conflicts:

  1. For EndNote 21 and earlier: Go to the Sync Conflicts group in your library, right-click on the group and select Resolve Sync Conflicts. For EndNote 2025: Click on Library Status and then Resolve Conflicts link
  2. A window will appear showing both versions of the reference. You can choose to: Keep Desktop Reference or Keep Online Reference. Note: the version that isn’t selected will be permanently deleted
  3. To resolve multiple conflicts: use the drop-down menu next to Skip and choose either: Keep All Desktop References or Keep All Online References.

If the in-text citations are not appearing correctly (e.g. displaying {ADDIN EN.JS.CITE} or long strings of code) and reference list entries are displaying with {HYPERLINK}, this means the display field codes setting in Word has been enabled.

To fix this:

  1. In Word, go to File and select Options
  2. Click Advanced
  3. Under Show document content, untick Show field codes instead of their values and click OK.

This should reinstate the correct formatting. If you are using track changes in the document, this may also cause issues with the field codes.

When using EndNote with Microsoft Word, it is important to make sure you are using the correct Cite While You Write (CWYW) toolbar. Using the EndNote Online toolbar instead of the desktop version can cause problems when inserting citations and may limit your referencing style options. If the toolbar in Word is labelled “EndNote” without a version number (e.g. “EndNote 21” or “EndNote 2025”), this means you are using the online version of the toolbar.

To switch to the desktop version:

  1. In the CWYW toolbar, go to Preferences
  2. Select the Application tab
  3. Change Application: to EndNote.

If you are using a footnotes referencing style (such as AGLC or Chicago Notes & Bibliography), you need to insert the footnotes using the Word References tab.

To do this:

  1. Make sure the required style is selected in EndNote and the CWYW toolbar
  2. Place your cursor in the Word document where you want to add the citation
  3. Click on the References tab and Insert Footnote
  4. In the CWYW toolbar, click on Insert citation, and search for the required reference
  5. Click Insert

The reference will be added to the footnote and it will create a bibliography at the end of the document.
