Collision not working when moving object horizontally

I have a board with cubes on top, when I move the board horizontally the cubes on top doesn’t follow. Checked everything about the collision box, if the board rotates, or the board is removed completed, the cubes fall, but if I move the board horizontally, the cubes on top it doesn’t react and just remain in the same place.
I have a video of what is happening now if needed.

Easier to see what’s up if you post your network .toe file

Until that time, see the many examples in Help-Operator Snippets for the Bullet Solver to get some inspiration.
