Extra 'label' node at top of DAG of GO terms

[avigailtaylor]

Hi,

I'm using the function godag_plot.plot_gos to plot a DAG of chosen GO terms. It mostly works, but there's an extra, unconnected node, at the top of the graph saying 'label' (see screenshot below).

Please could you tell me how to stop this from being printed?

Many thanks,
