The Member Formula Tab is not editable for Currency Dimension

Summary: When create new Currency Dimension we noticed the "Member Formula" tab is not editable (Greyed out)

There is no issue for other Dimension, we can change "Data Storage" to align with the value on the "Member Properties" Tab

If I remember correctly before 25_10 monthly maintenance it was possible to make change on "Member Properties" Tab for currency Dimension.

Content (please ensure you mask any confidential information):

Home page --> Create and Manage--> Dimension

Select the currency

Input currency

Select any currency

The property "Data Storage" : is providing to change.

BUT the member Formula has the same property "Data Storage" where it is GREYED out.
