I'm having that strange issue that not like written in the documentation, the order of the found corners is sometimes right to left, row to row like seen in the pictures. Does anyone have any idea why? (RED point is always first in array)

The chessboard detection needs an assymetric pattern (here).

Your pattern has an ambiguity (see the white / black squares):
