back log of info not synching

Hi All
I went away recently and couldn't synch while I was gone
I was wondering if MFP will synch the back logged info from my flex. I have synched now on my dashboard but it hasn't shown up on the last few MFP days yet.

Anyone else come across this ? Will it add back my exercise calories ?
I went over both days I was gone and want it to synch so I have a more realistic idea of how far over.

Thanks
