Wrong vis of tfr.plot_topo()

I calculated the time-frequency response, and use its method plot_topo to plot it.
This is the result.
I do power.plot_topo and power.plot([0]) both


The data is SEEG, I set the montage coorectly.

Any ideas about why this happen?
I run the demo and everything seems right.
