Localization UI text not working in SAP CAP BTP

[nikhil180490]

Hello ,

In my object page I have item table from which if user selects and click on Delete the confirmation pop up should show custom text as "Delete Article {number}?".

I have tried below text change in i18n.properties file but that text is still not changing .
With the same place I was able to change button text and other UI standard text but somehow this is not working 

Below is the code I have tried with 

C_TRANSACTION_HELPER_OBJECT_PAGE_CONFIRM_DELETE_WITH_OBJECTTITLE_SINGULAR|to_MucItems=Delete Article test?

C_TRANSACTION_HELPER_OBJECT_PAGE_CONFIRM_DELETE_WITH_OBJECTTITLE_PLURAL|to_MucItems=Delete Article test ?

# C_TRANSACTION_HELPER_CONFIRM_DELETE_WITH_OBJECTINFO|to_MucItems=Delete Article {0?

# C_TRANSACTION_HELPER_CONFIRM_DELETE_WITH_OBJECTTITLE_ONLY|to_MucItems=Delete Article {0?

# DELETE_SELECTED_ITEM|to_MucItems=Delete Article ?

# DELETE_SELECTED_ITEMS|to_MucItems=Delete Articles?

C_TRANSACTION_HELPER_OBJECT_PAGE_CONFIRM_DELETE_WITH_OBJECTINFO|to_MucItems=Delete Article ?
Where to_MucItems is the composition inside MucHeader entity 

Let me know if something I need to correct this or someone has a working example I can refer to
