Quiz scores and review scores are not equal. Why?

Hi maybe someone can help.  Why is my actual test score 100% when I view my results, but if I check my score with the "review scores" option from admin screen, it only comes out to 67%.....?  How do I get both to reflect 100%.  I am looking to use the auto grade function.  The drop down answers is not important as it's just gathering info. If I manually bump the score +1, that 67% won't increase (even with a refresh) to 100% but the answer gets a correct flag and I can see the "extra credit".  This is very confusing for such a simple app.

I get the same issue when I tried to use a branching question on another quiz.  It's not being scored in one scenario (person doing the test so they get 100%), but in review scores, it's counted as a question and it comes across as a missed answer or something, so the percent is off.  Thanks.
