Error message when updating subscriptions

Hi,

On the subscription page in woocommerce on the right hand side there is a payment schedule box. From here I can change the date and time for subscription orders. I normally can change both, press update and it gets updated without any pop up box. In the last few weeks, every so often I am getting a pop up notice from the ‘Price based on country’ with the following message:

‘Price Based on Country: Do you want to update the order lines with the price of the country before saving it?’

I don’t want to press ok just in case it breaks the system and changes the subscription prices. This seems to be linked to recent update, in the last few weeks.

Thanks,
Tommy
