Food Plan Confusion

[sixty3degrees]

Okay, so I'm very confused about the Fitbit food plan thing.  On the home screen it tells me I have 344 cals left, but when I click the tile it says there are 94 calories left in my budget.  I don't know which one to go by.  I have searched and read answers to somewhat similar questions, but it still is just as confusing for some reason.  Any helpful, clearer answers would be wonderful!

Thanks. I think I understand that part. I'm more confused about why it tells me two completely different numbers for how many calories I have left. What are those two different numbers based on?
