Mineshaft pillard not fully generate and mineshaft bug

Mineshaft pillars do not fully generate when they encounter water. They are then cut and do not touch the ground. The seed used is: -1192420621 and the coordinates are:  20  -20  367 . I want to clarify that I have activated the experimental gameplay of caves and cliffs. The mineshaft to the right of the bridge is also a bit buggy with its generation, it's like there's one getting in the way over another. The coordinates of the bugé mineshaft: 3 -19 382.
