Visual bug on shield

Dear Mojang, 

 

                    I have to report the bug on the shield. In third perspective view(front) and first person main hand, they look fine. But if you look at offhand(first person), the shield is not showing even I handed it. If I activated it, it's showing but different looks compared to main hand(first person). I have a screenshot and videos all about it. Hopefully you can fix the bug as soon as possible. Thank you! ☺️
