There are a few reasons why keywords may fail or be partially scraped:
There are no related questions/answers returned for the phrase (failed).
Google only returns a small set of related questions and answers for the seed keyword/phrase (partial).
Your internet may have momentarily timed out, causing Google to not return more related Q&A's (partial or failed).
You may wish to paste these keywords back into the Search Phrases Input field (1) and run the scrape again to see if the software can extract more questions and answers for these failed and partially scraped results.
