`practise` is a verb in British English and `practice` is a noun. https://www.google.com/search?q=practise+vs+practice&rlz=1C1GCEU_enUS821US821&oq=practise&aqs=chrome.2.69i57j0l5.5811j0j1&sourceid=chrome&ie=UTF-8    I think trying to make everything American English (`practice` is a noun/verb) is a pretty monumental expectation.  I can tell what the misspelled word is trying to say :wink:
