Custom Order Status and Woocommerce Email Template Customizer

Hello Team;

We use your plugin for our all email templates.
We also use custom order status as below;
Pending Payment
Payment Confirmed
Delivered

We have a new problem (there was no problem before);
We couldn’t see our custom order status in “email type” in your template. So we couldn’t select. There is only one option as “default template” and we have to select. And then we change order status to Payment Confirmed (it is just example) different email sent to customer as default template. Payment Confirmed template don’t send to customer.
We have this problem since when we edit template today. There was no problem before because Payment Confirmed template not selected “default template”. It shows just blank option.

could you please help us how can we solve this problem.
It is very important for us.
