Help Customizing Goals

Not looking to mentor nor be adopted....I just have a question and I thought this might be a good thread with lots of knowledgeable people Previously when using MFP I was able to customize my macro percentages (ie: i was able to have carbs reflect a lower goal number, etc). Some how when I came back after an extended absence my % are all back to the original formula. I can not for the life of me figure out how to customize it again....help?
