Dangling wires/extra net length using -sroute command

Hello,

I am using multiple power domains in my design and while doing the routing of power structures (using the -sroute command), I see that the VDD_CORE1 wire (in my case) always extends by a small margin beyond the power domain. Before running the sroute command, I use the modifyPowerDomainAttr commad to adjust the size of the power domain so that it sits exactly on top of the power rail I want to route. And then I use the sroute command.

But I keep getting this "dangling" wires which is leading to further DRC errors; also sometimes for the global PWR rails, the routing is incomplete leaving the nets unconnected.

Please assist me in this.  I am attaching a screenshot of the issue and the command I am using.

modifyPowerDomainAttr PD_1 -box 188 238 262 312 -minGaps {4 4 4 4}   // adjustPower domain to accommodate the VDD_CORE1 rail exactly

sroute -connect { blockPin padPin padRing corePin floatingStripe } -layerChangeRange { M1(1) LB(9) } -blockPinTarget { nearestTarget } -corePinTarget { firstAfterRowEnd }  -allowJogging 1 -powerDomains { PD_1 } -crossoverViaLayerRange { M1(1) LB(9) } -nets { GND } -allowLayerChange 1 -targetViaLayerRange { M1(1) LB(9) }

modifyPowerDomainAttr PD_1 -box 200 250 250 300 -minGaps {4 4 4 4}  // re-adjust back to original

Thanks,
