Nodes are centered by default (which seems logical). You just ask to _not_
center them... Just reread in the documentation the effect of the "offset"
parameter.

For \center, I do not reproduce your problem. I never use it myself
in the past (and think that the \centering macro is the "canonical" way),
but nevertheless you example give the expected result on my installation.
First check with \centering and otherwise investigate your installation,
version packages, etc.
