Alternating table colors not reset when longtable spans multiple pages

Question

I've searched and found similar issues, but nothing that really worked in my application. I'm attempting to generate a pricebook with images/specs in a caption of a long table. That's all working great, but I would also like to apply alternating colors. Works fine, unless I have a longtable that spills over into the next page. It does not seem to reset the row count number, so it just applies the next background color as though it were directly below the original table. It should be white for first rows after the header, but the second table has a gray background. Here is what should be a working example:
