It is quite often that some of your words are not allowed in AdWords, so you see them in AdWords as Bad words. You can see these Bad words also in your BlueWinston account (left menu > AdWords > Bad words).
Now you can add alternatives to Bad words directly in BlueWinston
Alternatives will be updated into AdWords account and maybe AdWords allow you to use these words. Try to use acceptable words.
During update from BlueWinston into AdWords, alternative words are accepted or not. If the alternative words consists some bad words, there are automatic requests for exemptions. If these requests are not accepted, the alternative is also marked as bad word and not possible to add some new alternatives.
