chunks shadows look strange

that black blocks in the fake chunks are there because i didn't torch the zone, but i already light up the area but seems chunks doesnt update, i tried destroy and put blocks in that chunks so maybe DH updates the chunks but it didnt, in fact, those dispersed blocks in the black area appear after i tried to updating chunks, like if DH just update that block position instead all chunk. a solution could be delete the data file of DH, but i am in a multiplayer world and I've already explored quite a bit.
