Bug: the currency in the subprocess changes when creating a subprocess from the parent "Order to the supplier"

How to leave the parent process currency in the subprocess (if this currency is not the system currency)? In the BP "Order to the supplier" at a certain stage, using the procedure button (Action when pressed), we create 2 sub-processes "Task for posting" and "Task for payment". When creating subprocesses, the system changes the currency in the subprocess to the system currency (by default), while the currency of the parent process must remain (for example, in euros) and mutual settlements on the Supplier's account are carried out in euros. Noted: - supplier's currency euro - euro process currency - marked in Action on click: "Add products from one process to another" ticked "Copy process currency and discounts from parent process" I think this is a system bug: developers help solve the problem!!
