Steps / calories- myfitnesspal sync

I’ve got an Approach S70 - I’m tracking my steps as part of my post surgery recovery, and I’ve been tracking my caloric intake on myfitnesspal

i recently connected Garmin Connect to my MFP account and it’s delayed but does seem to get my steps over to MFP

problem,is my watch says I’ve burned a few hundred cals (I’m currently power walking with weights), but MFP says 60

it seems MFP is just taking my step count and figuring it as a casual walk around the block. 

whats the point of connecting the two if accurate data isn’t used? Is there a way to fix this? 

im considering breaking the connection and just manually entering my caloric burn
