For some reason it won’t let me eat cake in survival

When ever I get into a world and I turn my self survival or If I’m already in survival and I make a cake it won’t let me eat it. But once I put my self in creative and I try to eat the cake it works. First the glitch was where I couldn’t get the cake in survival and now I can get it but I can’t eat it in survival. I tryed putting a little video but the thing won’t let me... so I will try to send photos of the video.
