s7 Spam moving failed

[AC Question]

Hello...after upgrading my OS on my Galaxy s7 to 6.0.1, I am having email problems. I am using the standard email app for an account through my domain via, set with IMAP protocol. When I try to register an email as spam, I get the message "move failed." I tried to move email to the spam folder, but there is no spam folder in the list. When I go to settings>spam addresses, the only editing option is to delete spam addresses already blocked. I am using the same settings I used before upgrading the OS. Anyone else having this problem?
