The turtle eggs and the sea pickles won't load correctly.

When i went on my Creative Minecraft world i wanted to make a pond. I got everything i needed, but then i decided that i wanted to add turtles. I spawned some turtle eggs but they wouldn't load correctly. One half of the egg looked normal but the other sides looked like it had layers. I thought it might have been a loading accident but then i put some sea pickles for light and it shows the same thing. I would appreciate if you guys could fix this issues because it's been bothering me now that i want make a pond. Thank you for your service.
