Disk Utility fails to restore my disk to single partition after removing a partition for Windows using boot camp

Removed the partition for Windows using bootcamp, the partition space went to a new partition named Free space.

Even the "Free space"partition cannot be merged with the startup disk manually using Disk Utility.

It is recommended to run a whole disk recovery or repair, which I have no idea how.

Running First Aid on the whole disk, error message as "Incorrect size" showed.

MacBook (Retina, 12-inch, Early 2015), macOS Sierra (10.12), Input method, Cangjie

Can you post the output of the same GPT command again?

This didn't kill the "incorrect logic volume" problem which fails the restoring process

The partition "free space" has gone, and i was able to repartitioning my startup disk back to single partition.

Thanks for your kind helps!
