Fandango At Home Catalog Chrome Extension Inaccurate

I love this extension but just wanted to inform people that currently I have about 1000 movies (that's excluding some of the featurettes that now show up) but only 854 of them show up on the exported spreadsheet. One set of films absent are the Amazing Spider-Man movies which are one of the sets that also shows the featurettes in my main list. Does anybody know why there's this discrepancy and if there's a way to solve it?
