In Tools -> Verify Design, when I run "Clearance" and "Connectivity" checks I don't get any errors but when I run "Plane" check I get bunch of errors:
Isolated Subnets for : GND
**** subnet # 1
Hatch Outline (110.1,120.34 L1)
Hatch Oultine (...., .... L1)
All of them are in this way. I don't see any problems in GND plane and no isolated copper. How can I fix this?
