The original error was on the second iteration of your cycle_vector
loop. The new error is on the first iteration of the loop.

I think your real question should be: why do sys.A and sys.B have 9 rows
in the first iteration of your loop, and 10 rows in the second and
subsequent iterations?

Maybe you can inspect the construction of your system in more detail and
see if there is a problem there.
