I am using Moodle version 3.9.4 and Questionnaire version 3.9.1.
I have an issue with a branching questionnaire,
My questionnaire has one parent question with two possible answers. Each branch has one child question.
Test 1
1. I choose option 1 in the parent question.
2. I answer the child question for option 1.
3. I go back to the parent question and change my answer to option 2.
4. I answer the child question for option 2, then submit.
Result: the responses to the parent question and the child question for option 2 are saved, but not the response to child question for option 1. This is what I would expect.
Test 2
1. I choose option 2 in the parent question.
2. I answer the child question for option 2.
3. I go back to the parent question and change my answer to option 1.
4. I answer the child question for option 1, then submit.
Result: the responses to the parent question and child questions for BOTH paths are saved. I expected to see only the response to option1's child question.
