When I press on some message to forward it, it shows me Random usernames of contacts I don't know. And it even shows some Mobile Numbers I don't know. For example, one number starts with +964 that's Iraq. I'm from Europe tho. These contacts and numbers are from all over the place.

Edit: This only happens on Signal Desktop. If I try to forward a message on Android it only shows my Contacts. And none of these unkown ones.
