Bob's Red Mill 1 to 1 baking flour

Usually I use my own flour blend, but I was in a pinch and acquired a bag of Bob's Red Mill 1 to 1 baking flour.

I made a few of my normal recipes with it, and each one of them turned out gummy. 

Looking at the ingredients list, the only thing I can think of is that it's too high of a starch ratio? Also, I read reviews online and there are lots of people who love it, so I'm not sure what's happening here.

All I know is that I'm not going to buy another bag because it did not work for me.
