I posted this question a while ago and found a solution.
I can't find a way to mark it as answered.
My hunch is because you cannot mark the question (the initial post) as the answer.
Edit: Also, you can only mark a response as an answer if the post is a question, not a discussion.
Please for the sake of others that might be searching the internet for the same problem/solution post an explanation of your solution as a follow up comment and mark that as answer. The follow up comment should then have a question show up for you as the topic starter asking "did this answer the question? yes · no".
