Post better photos describing your problem.
I have no issue with my Crank-2 system. Then again, I ordered the i-beam trussing first, then got the Crank-2 stands later.
Typically, the 4 brackets for the end have, on the "down part" of the T(the part that goes over the end of the i-beam) are longer than the cross part, if you measure halfway.
Can you even put the inner tubing inside and secure any of those bolts into position(the middle area)?
