Subscription Next Bill Export

Hello the community!

I am not sure which version of Infusionsoft I am using, sorry - this may be in the incorrect category.

On my contact page, under ‘Orders’, I have a ‘Subscriptions’ section with a ‘Next Bill’ date visible.

I need to export this field, but it does not appear in my field selection when running an export of ‘view subscriptions’.

Does anyone know how I can export this field please?

Thanks very much,
