40-Pin GPIO Header | Radxa Docs

The Radxa NX4 IO Board features an onboard 40-Pin GPIO (General Purpose Input/Output) header, providing a highly flexible interface for hardware expansion.

Are you certain that GPIO numbers and names are correct in this table? Seems that all these do not match to the NX4_IO schematic v1.11 pdf.
One more question: Are there GPIO PINS that are 3.3V or all of them are 1.8V and require level shifting to 3.3V?
