You have more than twice the lighting power in the west compared to the east zones:
And both of these use the same fractional schedule, which doesn't have a "Summer/Winter Design day Profile" to it uses the default run period profile for sizing days (for lighting people often set lighting to 0 for winter design day and 1 for summer design day in order to size for the worst case conditions)
Also, I would suggest you double check the boundary conditions of the surfaces in your model, from the picture the West zone should have a lot less exterior wall area than the East zone, but the table you pasted said otherwise (I don't have Sketchup handy to check that). That's going to make the east zone have more heating load though.
