E-mail signature when replaying an e-mail

When replying the e-mail, our company's e-mail signature goes on the bottom of the e-mail, not below our reply, even the account settings are adjusted correctly. It happens when we reply just from one of our e-mail addresses, other ones are functioning correctly- please have in mind that all our accounts settings are adjusted the same. Please see photo attached.

Thank you, Burow Dental
