It says literally in the known issues that quickbar 6 is missing...so obviously it's a known issue.

Daughters of Meridian are looking for active, friendly accepting players to join our little family. We are an LGBTQ+ friendly guild, and try to make a place people feel like they are at home. Few little points - Don't know how to do something? Just ask! We are more than willing to answer - Even if you're not a member hanging out in our discord! We compete in conquest every week with our flagship providing support on the attacking planet! Warzones, PvP, Operations, Flashpoints, Conquest we do it all! We are currently working on teams for a more structured approach. We have a guild flagship too! It has everything you can speak of. Including a cantina! We are not a serious group, however. We like to have fun and be sociable. If you have questions, the easiest way to get ahold of us is via our discord (link below), or message us in game by doing /who Daughters of Meridian. Any member can invite you or help answer your questions! Thank you for taking the time to read this and have a great year! Discord: https://discord.gg/HKvKBBd Website http://dom.aethro.net

If it was in maintenance mode it wouldn't get any major updates or content at all. It would get little things once every year or so, maybe some additions to the cartel market but that would be it.

This post made me and my roommate laugh Oddly enough though, I think a good chunk of the country probably feels the same way you do lol.
