Using a Retake Response Link for Multiple Survey Respondents within the Same Survey?

I have set up my survey to work like an application system. I have everything down perfectly except for one minor issue that I cannot figure out? Within this survey I can route it in my survey flow through a ?Q_R= retake response link, within email actions, to go from 1. Student 2. Approver One 3. Approver Two. 4. Everybody receives a final copy. I only wanted approvers 1 and 2 to see a summary of the student's responses, so I used embedded data (partially including an API from our banner system) to pull answers in so the approvers didn't have to go through all of the student's previous answers before getting to the approval question they have to answer. This all works great. I do, however, have a unique situation though where a few of the applications only have one approver instead of two, so I did another flow process where it would just go 1. Student 2. Approver 3. Everybody receives a final copy. Again, this works too, with one small exception. In my email action after the student fills out their part which should only go to the approver once, the same email action is sent twice for some reason? The first email gives them the option to approve or deny. The second email (again, it is the same email action as the first one) then goes to the same person showing them their recently submitted answer, before it can be finalized and go on to the next action where everybody receives a final copy. Any ideas? I would really hate to have to make to separate surveys for this unique situation if this can't be done. I will post my survey flow. Thanks in advance for your help.
