Half of things disappear from Big Chests

I'm having a very annoying bug in my Minecraft, this is the following:

When filling a "Big Chest" with objects, half of the items previously collected disappear (when leaving and saving the game) the truth is that this bug is quite annoying since the things that have cost me to collect disappear. It should be noted that this only happens with large chests, the singular chests do not disappear the items (even if it is full).

The Images I show take place in a creative world but this bug affects all game modes (creative, adventure and survival).
