This an old question from before the site update. So the responses do not always post in proper order....I believe it is a formatting issue from the old site. Any question from 2016 is likely to have the same issues.
If you are not getting alerts to you answers to your questions make sure when you respond to an answer that you do not "unsubscribe" yourself from your question.
I do not ask that many questions so out of habit I uncheck the box for Send me notifications when other members reply to this discussion.
