Thunderbird creates spam folder when I already have a junk folder (bug1985372)

I use Thunderbird desktop to access IMAP email from my hosting provider. My hosting provider includes a junk email folder named "Junk" with the path "...hosting.com/INBOX/Junk. I cannot delete this folder. Whenever I run Thunderbird, it creates a second folder named "Junk" with the path "...hosting.com/INBOX/spam. If I right-click on this folder and delete it, it is re-created the next time I start Thunderbird. I have gone into "Junk Settings" unchecked the "Move new junk message to..." checkbox thinking that this is causing Thunderbird to mistakenly create an extra junk/spam folder but it continues to create that extra junk folder. How do I stop this from happening? I should only require one junk/spam folder.
