Getting Welcome new subscribers email automation again if customer already subscribed

Hy,

I have one issue if a customer already subscribed to our newsletter emails and again if he will place order from our store and check the newsletter email checkbox at checkout, he is getting gain the same automation(Welcome new Subscribe) and its going on loop if same customer orders next time.

My concern is customer should get the email only if he is new subscriber while placing the order. Should i need to put some specific condition to my email workflow.

Here is my workflow

Here is my condition
