Every now and then you will get this bug or glitch, I usually log out real quick and log back in to fix the issue, and if it persist I notice ping and lag related. But this plague will continue until they fine a permanent fix to it, but for now we can only find ways to work around these game breaking problematic that occurs here and there sadly....

You character or player have to be at the side of the trunk to open up the inventory via Tab button or you could open up the trunk from the back like in real life and Tab target the trunk to be more immersive. The Sarka 120 holds about 300 inventory last time I check after the 1.05 Update.
