I think Thunderbird had a recent update because all of my folders are a jumbled mess.

I have no idea what happened to my Thunderbird. I think it might have been an update, because all of my folders are not where they were, everything in the folders are sorted by groups like today, or older. I noticed a bunch of my emails are now in folders marked as a Userfolder#. The emails it contains are those that normally should be in a properly named folder, only those named folders are grayed out. Another issue is that when i try to open an email, it opens it as if I want to reply to it. If I just want to read the email, I have to right click on the email and select open to read it. I have 2 spam folders, no idea why, nothing saves to my draft folder I found out today, I just dont know what happened! I dont think I did anything but I dont know now, as Im beginning to doubt myself. It's been this way for a few days.
