I think you would first need to find out more about what is going on.

Was the asset "placed in service" before 2018?  If so, my GUESS is that is just a weird way of showing they took the 50% Special Depreciation Allowance.

If that doesn't seem like it would apply, it may help if you tell us when it was "placed in service", and exactly what the asset is and what the asset is used for.
