Adobe Acrobat Sign issue when same user needs signs workflow more than once

Hello,

I encounter an issue with workflows when a user needs to sign a document more than once. I was able to replicate the issue with the user and what appears to happen is the following:

1. Signer 1, Initial signature works fine and the document gets passed to the next person, this is updated on the Adobe Acrobat Sign "Manage" dashboard. 
2. Signer 2, Next person signs the document and now previous person needs to sign the document again, this is updated properly in the manage dashboard.
3. Signer 1 and SIgner 2 can see that the document needs to be signed by Signer 1 again, but Signer 1 does not have the option to Sign the document via the Manage dashboard. 

Only way around this seems to be that the signature request email does appear to go out even though the Manage dashboard does not reflect this. If the user uses the link in the email then they are able to sucessfully sign the document and the workflow continues.

Is there something I am doing wrong or something that can be done to prevent this issue? 

Thank you.
