Acrobat Pro - Request e-signatures signature field for Digital Signature is not available

Dear

My organization wants to start using digital signatures. We can already sign with a digital signature with the 'Add certificate' tool. I'm also testing the 'Request e-signatures' tool within my Adobe Acrobat Pro subscription. Now I'm running in to the issue that some options are missing that I have seen available in  screenshots and in Adobe documentation. In the 'Prepare' step you normally have the option to add 'Digital Signature' under signature fields, but I am however limited to the options 'Initials' or 'E-signature' both in the desktop version and in the web version.
