fitbit and myfitness pal

I don't know what's wrong but I got the flex wireless activity and sleep wristband and for 2 days now It does not show that I exercise in my fitness pal..

If I log in to fitbit it show that my exercises sink to it but on my fitness pal It how like 0 exercises it just been like this the pass 2 to 3 days I think

I not sure how to get this to work anyone would know

Thanks for your help
