Leveled vs. Levelled
“Leveled” and “levelled” are regional spellings of the same past form. Cambridge distinguishes US “leveled” from mainly UK “levelled,” so the choice is regional rather than semantic.
Use “leveled” in US English and “levelled” in UK-oriented English, unless your house style specifies otherwise.
