Dropdown Conditional Fields including more than what I intend

I work in our companies AP Department, so the forms I am getting signed are high-cost invoices that need approval before they are paid. Most invoices are valid and are to be paid, but occasionally invoices are not valid and therefore should not be signed. I set up a dropdown with 2 states, Approved, and Disputed. When Approved is selected I have the conditional field set to reveal the signature box, and when dispute is selected, A box appears with “UNDER DISPUTE” in bold.

The issue I am running into is that the dropdowns all become connected to each other. I imagine its because I am merging the recipients? Each envelope is a stack of 3 different invoice types that need to be signed off on by 1 to 2 people, with a specific signing order. I use templates for each of the invoice types, but all need to go to A, then some need to go to B when A is done. I HAVE been checking “Set Signing Order”, then changing all of the A signers to 1, then adding the B signer and setting them to 2. I then get the prompt to merge the recipients and do so, since all the A signers are just the same person. I imagine I still need to do this step, can the dropdown be configured in some way that each instance is specific only to the invoice its on, and not revealing the signature line on every single invoice?

Hopefully that made sense, I worry I started getting a little lost myself by the end there. Any advice would be helpful!
