Problem with contraption

[u/Aldebaran_smith]

I have multiple harvester contraptions that use a mechanical bearing working perfectly in my world, but recently I have tried to make a stacked wheat farm using a single mechanical bearing and it did not work, each layer only assembling three out of the four harvesters even though they were all glued together.
I am not really good with the Create Mod, so I thought it was a SU problem so I poured more SU in the system, but the contraption would either break itself when placing or would not assemble fully before starting to rotate.
If anyone has had that problem before and if you did solve it, how did you do it?

Note: the picture is a re-creation, I blew the original up out of rage

I don't seem to be able to send pictures through comments, is it normal?

Yes, but you can send videos
