3483757 - 'Order quantity' and 'price unit' fields are showing many zeros in Purchasing Fiori apps - SAP S/4HANA

When displaying a purchasing document (e.g. purchase order, purchase requisitions) in some Purchasing Fiori app (e.g. My Inbox app, Manage Purchase Orders...), many zeros are shown in the Order Quantity and Price Unit fields, like: 

Order Quantity 1.000.000,000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 UoM
Price Unit 1.000,000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 UoM

The issue does not occur in the GUI, only in Fiori apps.
