Stop ignoring/moving conversations

I’ve been using the the “Ignore” button on some conversations hoping to get rid of some “noise” in my Inbox and created a “Move Conversation” rule on some other messages. However, some conversations went back to an interesting topic again and I want to start receiving them in my Inbox again.

I’ve looked at my list of rules, but I cannot find any rule in my list of rules which is responsible for moving/deleting this conversation.

How can I stop ignoring/moving a single conversations or stop ignoring any conversation?
