Turmeric

How do you spell the name of the spice "turmeric"? Apparently not like "tumeric." Wikipedia says:

Its active ingredient is curcumin and it has a distinctly earthy, slightly bitter, slightly hot peppery flavor and a mustardy smell. Erode, a city in the south Indian state of Tamil Nadu, is the world's largest producer and most important trading center of turmeric in Asia. For these reasons, Erode in history is also known as "Yellow City"[citation needed] or "Turmeric City"[citation needed]. Sangli, a town in the southern part of the Indian western state of Maharashtra, is the second largest and most important trading center for turmeric in Asia.*

Another site noted it is often misspelled as "tumeric." So McCormick must have realized their mistake and fixed the spelling on their label, but not their display:
