Similar Rigib body animation not working for other objects

simple animation the puzzle block with spin and move to y axis to the holw in which they fall
theres a contraption that prevents the blocks the fall to infinity.
every block falls in as they should. but the 3rd block from the right when it falls it it twists a bit and the platform does not have a rigid body so both overlaps.

then i deleted the 3rd row entirely and duplicated the 1st then the 4th one one after the other but both rows had the same issues even though they didnt had those problems in their repective positions earlier. im so confused
