It's a minor bug, and I can confirm that it's one that happened only after Patch 2 was released. It's supposed to be showing whatever the mapped key is. For example, I got that bug when the pop up for the crafting materials appeared early on. This was when I was playing a new character last night during the prologue. I know it's supposed to be the "I" key, but it went weird for some reason. I hit the key and it wouldn't register. After about 20 seconds, I hit the I key again and was able to continue.
Not sure about the camps part, but I've been wishing I could disable the tutorial popups for subsequent games.
