Ok so sometimes my WiFi goes into some weird low signal mode where normal words work but realms specifically don't work. I can still join worlds of my friends and they can still join mine. I noticed that when this happens, my inventory seemingly gets "cleared". After like 3 times of this happening, I started seeing a pattern that when my Wifi got glitched out i would have a seperate inventory/e-chest. So basically I would have 2 separate inventory's and e-chests in one world with the same account.
