[Gelöst] currency display

Background of the issue:
I am trying to show AED currency when the website is in English. I already opened a past previous ticket with it: https://wpml.org/forums/topic/currency-and-footer-menu-rtl-alignment/

Symptoms:
I expected to see AED currency for all products. Instead, I got: د.إ

Questions:
Why is the AED currency not displaying correctly when the website is in English?
How can I ensure that AED currency is shown for all products?
