Fitbit flex negative adjustment

Hello everyone ,

yesterday I logged all my food intake for the day and it was 1320 kcal.
My exercise -954 , net 366 and remaining 834.
*Fitbit calories burned 2854
*Mfp 1900

I red the atticle which talk about negative adjustment but am confused now after seeing those numbers !
Dose that mean that I have to burn 1000 kcal more a day to reach my goals ?

Thanks in advance .
