problem updating references

Hi folks. I’ve been adding some DOI numbers to certain records and then trying to check them with the “Find Reference Updates” feature. However, the records that are being suggested by way of updating seem to have nothing to do with the original record!  For example, DOI 10.1021/es070763n is an article titled “Chiral Source Apportionment Of Polychlorinated Biphenyls To The Hudson River Estuary Atmosphere And Food Web” form 2007, but the reference updates feature is matching it with a 1975 article titled “LYSYL oxidase dependent synthesis of a collagen cross-link containing histidine.”  Any idea what’s going on here, or how to fix?  Thank you!

Well, unfortunately, this is what I seem to get… I right-click on the entry of interest, select “Find reference updates” and get this result.
