Anothr FitBit question

I can;t find an answer on the FitBit group. Here it is:

I have the FitBit Aria scale. Nothing to keep track of things, etc. My question is, it still adjusts my calories daily here on MFP. I only log ANYTHING on MFP, but still, isn;t this essentially doubling up my calories burned? Can I turn the feature off? How so? Thanks!
