To explain the title in further detail, earlier today I was clearing out a couple spam emails from my inbox, and on one of them I accidentally clicked "always showcontent from this sender", or something along those lines.

Annoyingly, I'm now receiving more messages in my inbox, all claiming "This sender is in your contact list" under the additional header info, despite each of the corrisponding emails being from a different address. Of course, I immediately checked my safe senders list and contacts list to see if I could locate anything unusual to remove it, but this was a no-go.

Is there some other method for removal I'm not aware of? Or better yet, why isn't there a button for reblocking senders within the same email?

Some assistance would be appreciated.
