Hideout item slot not working

I have elite skill in hideout management. The hideout has extra slots for items.

The generator's slots and water filter's first slot still works sometimes.

But the rest of the time it encounter errors and the game has to be restarted for inventory to work again.

Thanks.

Seems like the slots from hideout management is causing the issues.

Here you go. Thanks.
