Text on signs dissapear shortly after clicking done or escape

Hello so I have encountered a issue regarding minecraft realms. This issue is based on the text displaying on the signs. Iv tried multiple things like opening or using a other world or checking the world settings and refreshing the realms many times. Tried once opening and closing the realm. But works perfectly fine in singleplayer and other mulitplayer server. I would like to have this bug fixed asap! I have also seen other players complain about this in the community servers but now im sending this directly just to make you guys more cautious about this, its very annoying. Best regards Tommy
