The Library provides some modified and additional Filters, Connection, and Styles files.
Note that any zipped files need to be 'unzipped' i.e. right-click and choose the extract command. Copy these files to your EndNote file folder location.
If you just need the APA 7th style, note that this is not 'zipped'. Just save it into your styles folder.

When field codes are removed, the link to the EndNote library is removed. This should only be done as a last step, after the document has been formatted in the style you selected. The document is saved as a copy and converted to formatted text. The document cannot be reformatted later.
To remove field codes
Keep the original document, as it is the master copy that you will have to use if you wish to add or remove any references using EndNote.
