Sales Order Entry - Deposit Payment Type field

Hello,

In AR -> Setup -> Payment Type Maintenance we have the following Payment Types created for this one particular company

I need to update these payment types but more importantly, I am trying to determine where the Deposit Payment Type values shown below in SO entry with this same company are being pulled from.  I would think these selections should match what is showing above in Payment Type Maintenance but they do not.

Does anyone know of somewhere else I can validate the options showing on the dropdown (NONE, CREDIT CARD, CC, and CHECK)?

Thank you in advance.

Scott
