Analysis of an electrical network on a topological basis and inconsistances.

Hello everyone!
In the attached photo, I perform a topological analysis starting with the graph of a given system. At the end of the calculation, the two matrices β.t and Q.f should be equal, but instead they are different. Why?
Thank you to everyone who will respond.
Bye!

I chose a new tree with no problem-causing configurations, the results are perfect.

The two matrices differ in exactly one position (indices 11,17):

Yes indeed! I'd like to know why this happens? the equality of the matrices must hold.

I think the tree I chose (orange branches), among the many, isn't right. I'll try changing it soon.

(...and changing the tree means starting all over again....)
