Problem with ignore

A couple of guildmates of mine have run into the issue of me being on their ignore lists but not visibly so.

They will send me tells, which my ui auto-opens in a new tab so that it is easy for me to see individual conversations. I will reply there, but they don’t get those replies.

When I go back to my main chat window it informs me that “xx-BleedingHollow is ignoring you.” I have confirmed in discord and guild chats that they do not have me on their ignore lists.

I don’t have them on my ignore list, either. Add-on disabling does not seem to have any impact on this issue.

The first time it happened last expac it actually caused hurt feelings because I thought the person was mad at me. This time it is just causing a little confusion, but it may cause problems with things like raid invites and loot trading going forward.

If anyone has any suggestions for how to fix this, please do let me know.
