Confused about a food grade...

So, I had manually input my dinner (Healthy Choice Golden Crusted White Fish) and it had come up with a grade of A-, yet when I add it to my food log, and then view said log, it's showing as a B. This is very confusing to me and I was just wondering if anyone else has had a similar issue? And, if so, why is it showing two different grades?

The grade changed just for that one food or did your whole grade change?

is that a custom food?  I've never seen that happen with a database food (although, it's probably possible).

It changed for that food only. After inputting all of the nutritional information, the grade was an A-, but when viewing my food log, it was B. And yes, it was a custom food. I just don't understand what would make the grade change. Even now, if I click on the food in the log, it will give the A- grade, but still showing a B in the log itself...
