Downgrade Household, can't save

Hi,
I created my account using the Android app. Now, I need to tune my envelopes and accessing via web I see that there are all the envelopes I created at the beginning, whitout updates. When I delete come envelopes to downgrade to free, I can do it BUT the “SAVE” button doesn’t work. Can you help me, please?

Sorry for the trouble! Can you email us from the email address you registered with so we can take a look?
