Email subject placeholder not working

Hi

I’m trying to set up all the emails in woocommerce and e.g. on emial New Order to admin I set the following placeholder:

New Order! {order_number} – {order_date}

But when I make an order I get the following subject in my email account:

New Order! {order_number} – {order_date}

So in this case both placeholder are not working

The subject for the processing email I set to the following: We got your order! {order_number} – {oder_date}
and I get the following: We got your order! 11956 – {oder_date}
So in this case just the order_date is not working

I’d be very glad of any help

thank you
