    The image you have attached looks like complete routing is done instead of just sroute. If you have issue with sroute, check you Macro LEF to see if those power/ground pins that you are trying to sroute are indeed defined as POWER/GROUND. Secondly, you need to verify that GlobalnetConnect has been applied to power/ground pin of your MACRO. For floating signal nets, you could check the netlist if there is a net connection.
