or you have any vest or jacket in your inventory and you have to look if the canned food is there.

or it is outside at the entrance of the building, it is a desync bug with doors or something similar. Note to Devs: Please make close range-checks for "doing something" with all items, too.
Also there is a bug where containers/clothes stay invisible in vicinity and visual on the ground when you dropped them. When you re-log it will be there. Though, these are already known bugs.

Hello JohnnieWalker and thank you for the report.
This is an issue we are aware of and it has been scheduled for a fix.
