[BUG] Running 2 circuits and changing qubits outputs wrong result dimension

[visagim]

Expected behavior

Running attached code should return a 2*2 array

Observed behavior

Instead we get a 22 array for the first circuit and a 32 for the second, where we have changed only one of the qubits (but we still have 2 qubits)

Output of the code below:

There's probably residual data from previous acquisitions.
