It's not just you. I've been complaining about them for months now - they're all off-centered and several of them are sized oddly as well. They haven't been right (with one or two exceptions) since the time they started this new goal structure that uses the Collectibles to make appliance parts. I figure they must've made some changes in their office and the people now in charge of goals are the reason behind the change.
In all my years of playing, I can't ever recall this being an issue before and it sadly doesn't seem like it's going to get better any time soon. I've not used one of these new wall decos in my bakery and I won't so long as they're so glaringly misaligned that putting them on the wall makes the area around it seem off kilter. And the fact that I have to shell out 44,000 coins every goal for these eyesores is salt in the wound for me.
