Email invoicing

I used to be able to just type in new client's name and email address and proceed through completing the email invoicing form easily. 

Now when I type in a new client's name, a very long form with lots of fields pop up and the ease of just typing in the client's name and email address is gone. 

Pls help! 

I had also today connected my quickbooks with my bank accounts to enable me to receive bank transfers. But even went I turn off that function and just accept credit cards - it still produces a big long form for me to fill out. 

Pls help!
