Pages no longer centered when moving project from Axure 8 to Axure 10

We recently moved a large project from Axure 8 to Axure 10. We had all our pages set up as centered in Axure 8, but when we moved to Axure 10 the pages seem to be all over the place. The pages that are full screen work fine, but the ones with small widgets do not align center. If I change the page to be aligned left it then seems to be more centered.
I am looking to see if anyone else ran into this issue, and if there is a setting we can change globally - or I guess page by page - that would make all our pages centered again when previewing and publishing. I tried a few different Page Dimensions but still the same thing.
