Issue with Customer Retainers

Christine_B

I have a client that paid a retainer and I followed the instructions here: https://support.waveapps.com/hc/en-us/articles/208622916-How-to-handle-invoice-deposits-or-pre-payments

When I record a payment to their invoice and I check my balance sheet it increases the liability in that account instead of decreasing it. I also can't quite figure out (other than making multiple journal entries) how to easily move those funds from my retainer account to my operating account in order for the funds in each account to be accurate.
