these errors appear when you define power and ground port names in DRC setup.

IO, typically, has multiple ports with same name, not all structures has connections by metals (breaks according to tools), all structures will be connected in full ring IO+power PADs. For clear DRC you need to connect all ports by RING PADs or by metals.
