#Product#Product & Service New

I've written an Apex class with methods that parse data out of a CSV file, create account and contact lists with custom fields used as external IDs, and upsert that data using the custom fields as the comparison for duplicates. However, Apex thinks the data in the contact list contains duplicates. I have confirmed in the file itself and via debug code (comparing against a set) that it does not, and I can see when I write debug code to only add the contact to the list if it is not already in the list that Apex thinks every record is a duplicate. 

I've written code to ensure and confirm that the list is empty before I start adding to it, I've edited the match rules so they only match on the external ID, and I've uninstalled Dupe Eliminator and Duplicate Check (installed by my predecessor) to be sure they aren't creating restrictions I can't access. Also, I've tried to check Apex triggers, but they are managed and can't be viewed/edited. We do have quite a few other packages/apps installed. Could these be the issue? Could it be a scope of the variable issue? Does anyone have any suggestions on what else might be the issue? 

I am including my code below with the caveat that it is pretty messy right now with all my debug code, comments, and variables for other methods in place. Below that code is a screenshot of the debug log starting at the beginning where you can see the first test for the contact existing in the list results in TRUE, before any other contact has been added to the list, and that there is no debug output for the code outputting

 any contacts already in the list before I start adding to it. Finally, I am also including a screenshot of our installed packages.
