So, while playing Minecraft today, I ran into something that I consider a bug. When trying to type uppercase letters or characters like ! or $ with the shift or caps lock key into a structure block nothing happens, although if caps lock is on and I type with the shift key, I am able to type but the letters still don't become uppercase and still no characters. Not only that, but the space bar doesn't work either. I've even tested this in command blocks and signs and everything works like it should. Also, this only occurs in the save, load, and corner mode. I can 100% ensure you that my keyboard and/or OS have NOTHING to due with this. Please, if anyone can respond or if something similar has happen to you, please do tell me.
