Robots.txt Disallow Product Pages

[EricApex]

Hello,

I recently noticed that the our robots.txt file is disallowing a majority of our product pages.  I found these pages in in our robots.txt.liquid file.  

domain - apexphotostudios.com

The pages in question start at /products/rooftop-a thru the bottom.

Is there a technical Shopify reason for why these are blocked?  From what I can gather they were added by the person who was previously in charge of managing but I can't find a good reason why.  I have since added a new product page which is not listed here so it doesn't seem to be trigged by Shopify itself from what I can gather.

Any assistance would be greatly appreciated.
