Yes, usually that's the case, but for this post it just says REPLY with no options. The EDIT option is gone on all of my posts in this particular thread.
yes that is weird. It is like it is not recognizing you as the author of the post. I've published two significant updates in the past 10 days or so. It may be you have a cache of something old in your browser cache. Try a hard reload of your browser holding down the shift key while on that page.
