As explained in this thread (https://support.tipsandtricks-hq.com/forums/topic/emember-feature-requests) we now have a new version of eMember that will definitely solve this Interface issue. The question is do you want to upgrade to the new version right now or not. Upgrading to the new version is definitely good but it means the pasword for existing users need to be reset/changed since the new version now uses the same password encryption algorithm that wordpress uses (this was necessary to make the wordpress user integration feature happen).
I can give you a script that will automatically convert the member passwords so you can do the upgrade too (this option is good if you have a large number of existing members already)
