Minecraft 1.19 burried treasure Maps

Hello,

I just tried the Minecraft 1.19 Version in a singleplayer World for a youtube video and I found a shipwreck on the ocean. I looted it and even got a burried treasure map. I tried to look at it, but it only looked like a piece of paper in my hand. I thought this was part of the new Update and you have to right click it to see the map, but when I right clicked it, it made a normal map of the position where I was, without any red "X". I put a picture of the so claimed "burried treasure" map in the Appendix.

(sorry for my bad englisch btw, I'm german)
