How to remove double DOI in reference list

Hi, I have problems with Endnote 14 referece list.  I have modified Vancouver style to to include DOI and PIMD by inserting the fied. The template in the style editor looks this: Author. Title. Journal|. [Type of Article]|. Year| Date|;Volume|(Issue)|:Pages|. PIMD: PMCID|. DOI: DOI|. However, in the reference list  I have double DOI field, eg.: “(…) Sep;xx(9):5xx-5x. PIMD: 73xxxxx. DOI: 10.10xx/z4xxxx-02x-04xx-9
10.10xx/z4xxxx-02x-04xx-9 [pii]”.
Any ideas how to remove the duplicate?
