Payment Module on v5.4.8-C86 missing Amount field


I just updated the app to the newest version, and lost a very nice field on new payment call " amount", how do I get it back to the version v5.4.8-C86?

See attached pictures for details
First picture is the old version


The field confused some people so we made it optional.

You can enable the ‘enable applying payments’ options on Settings > Payment Settings to add it back.

Got it
Thank you very much
