Switch and Do until problem

Hi, i have a problem, i made a workflow that need to pass thru 3 states.

it starts and it's ok, goes thru the first state ok, but when it needs to change, finishes, i made a mistake?

i set a variable to ose in the do untiland conmutatorassign the variable to both elements, when the variable becomes "Finished" it should en the loopat the end of each branch the variable changes to next state (it's the same because i copy and paste it)

a vaiable is created and asigned like the first branch, i asing it to work in the do until and the switch (is t a good practise?) the workflow goes thru the branch and at the end it changes to the next state (it is ok bc i copied it)

something missing?

Thanks!
