ah, ok it's probably because the "put" overrides the \center. However, Perhaps there is a way to change the LaTeX export to include the centering inside the box. Right now it looks like this:
\put(3001,-6549){\makebox(0,0)[b]{\smash{{\SetFigFont{12}{14.4}{\rmdefault}{\mddefault}{\updefault}{\color[rgb]{0,0,0}sdfsdfdsdsf}%
