"MANADALAY" postmark named wrongly

While introducing new and standardized postmarks in 2018, Mandalay GPO has an interesting event. One of its new postmark comes with the wrong spelling of "MANADALAY" instead of "MANDALAY".  Once public and officials noticed, it was widthdrawn from GPO.  It was used about a month, I believed.  As Mandalay GPO is the high grade PO, it has more then one set of new postmark.  I have also received one postcard with the correct town name which was used on same day.  The wrong and correctly spelled postmarks are compared below.

The new postmarks were introduced on 9 Oct 2018. The new set of postmarks (Burmese and English) were distributed to 778 full service post offices around the country.
