Unable to type certain characters like nani/choshi etc in japanese ime

hi friends, I’m presently learning Japanese 1 by memrise

I have installed Japanese IME on windows 10, howver I’m unable to type certain characters-eg nani, choshi,genki desu - windows should supposedly automatically covert it to Japanese when I type in romaji however it doesn’t

do any of you have the same problem? what did you do?

Press Shift+Caps Lock to switch between Romaji and Hiragana. To get the Kanji, type what you want in hiragana, and then press Space. (You will get Kanji suggestions)
