Truss system not "connected"?

[ticorules]

I have 3 sticks of truss connected together, using the magnetic feature, they attached together. I added fixtures to it. Hoists are also connected. if I go to a hoist to change trim of it, it will only move the stick of truss directly under it. I figured a quick fix would be to delete the hoists, select the other 2 pieces of truss and move them away and then one by one, connecting them again via the red magnetic line to attach to the truss, then once again adding hoists. Doing that did not seem to fix the issue where changing hoist trim does not keep the entire system together. Any ideas what it could be?

use the change trim height of system command in the truss object properties, this will move the entire truss line and adjust the trim height of the hoists without disconnecting anything

Hi, thanks for the response. I did that and that is how I noticed that for some reason even though the trusses will auto connect, when I do the change of trim height in the truss objects properties, the whole system does not stay together
