Thank you this info. It worked for me.
I cleared the cache and the word suggestion was removed from the list BELOW the input text line, but it still showed the prediction ON the input text line (if that makes sense, underlined word suggestion on the input text line that you can override with a suggestion from the list below). I had to go and reset the prediction settings, like the original poster did, in order to remove it from ON the input text line.
Basically it appears there are 2 caches one is for the "dictionary" suggestions BELOW the input text line and the other cache is for the predictions ON the input text line. To fully clear your suggestions you need to clear BOTH caches.
I agree, this is a step backwards from just long holding the word and deleting it on it's own. You must clear the entire lists.
