Adding words automatically

Need to see why my SwiftKey is adding words to my sentences? I have looked at the settings and cannot see anything that would allow this. For example if I type "hello how is it going" it will type "hello how is everything it going". I don't want this feature, why would anyone? It is adds the word "everything" in that example. I'm constantly having to clear the memory, which helps, but it still should not be predicting my sentence and adding words. I use flow mostly just so you know
