Amar or Omor Ekushey?

A report by BSS-Dhaka about celebration of Ekushey in our missions abroad, published in a local daily on 22nd February, began as follows: "Amar Ekushey- the International Mother Language Day......etc." I was somewhat confused, as I believe it should have been "Omor Ekushey" and not "Amar Ekushey"; as phonetically the meaning of the two words differ markedly. While "Amar" in Bangla means "Ours", "Omor" means "Immortal". I believe we mean "immortal" and not "ours"; more so as the day is now recognised internationally.
I believe if the publication of the report is correct, and there has been no spelling mistake while printing the report, BSS needs to issue a correction; and possibly an apology for this major mis-representation of an important event's underlying meaning.
I shall be obliged to have readers' views on this issue. As a university student in 1952, I feel strongly about it.
