Remove all manual formatting from your text (which is indicated with a "+"), delete generic generated character styles and build up your proper paragraph and character styles. Take observation on the basic character properties where you will find no break in both stye categories and in the keep options of the paragraph styles.
Never have any text without paragraph styles, never any exception of formatting without a character style and don't use imported Word styles without checking and edition in InDesign, better is to avoid imported Word styles.
