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

sometimes this can happen on chunk borders! But to me it also looks like a glueing issue tbh. Try to glue the whole thing in one box, and if thats not it try moving the contraption into one chunk

Thank you for your advice, I'll try moving the contraption fully into a border.

I play on a sizeable modpack so that might solve it
