House Inventory Items Vanish

I am not sure how it is happening, as Im not seeing it occur, I am noticing it when I come back to my storage later.

the first time it happen 800+ steel and some Armor Plates were gone.

This time a dozen phones and a few hundred oil is gone.

But its almost like 2 random blocks of house inventory just delete themselves. This time around its more easily replaced but I am not sure what is causing it to happen.

I opened it earlier to grab a repair kit and a redbull came back later to put something away and noticed the blocks were empty where my Phones and Oil go as I keep everything organized a certain way.
