@RAPHAEL_KENYA_SWANZY, there’s been no change in inventory, it’s only a change in the display of calculated columns.
See this topic:
Rest assured that no update so far – and most certainly not in the future – would ever change user inputs, so there will not be any loss in data. In case the processing of these user inputs is somehow seen unfavorable by the end user, all changes can be undone either by the user or by another update. This have been a foundation of Manager that’s never been broken.
