Searching for membership records

Hi there
I have a new membership community and the subscriptions are managed by Infusionsoft e-commerce.

I have two subscription types - monthly and quarterly. I’m trying to amend the next payment date of one of my quarterly subscribers to the following month, but when I do a search on subscriptions I’m only seeing a list of monthly subscribers.

I’ve done everything I can think of, but I just can’t find a list of quarterly subscriptions. And when I go to the member’s individual record I can’t find any way of amending the date of her next subscription.

Can you help? The majority of my subscribers are quarterly so this is a significant problem.

Thank you
