Problem
The currency symbol in the Discount amount field looks wrong.
Possible cause
The currency symbol is fetched from your chain's default currency setting. If it shows the wrong symbol, the chain setting is likely not configured correctly.
Solution
Contact your administrator and ask them to check the chain settings.
The administrator needs to update the default currency to the correct one.
If the problem persists, contact support and include details about:
Which currency symbol is shown.
Which symbol you expect to see.
When the issue occurred.
