SeemsIt seems like there is a defect with how the terms are searched. When you use a word that shows up in an answer and not the question, the answer is replaced in each subsequent answers.
For example, try searching for the word "test". Cat1 - Title1
Cat1 - Title1 will open up and show the answer. However, if you now expand Cat1 - Title2Cat1 - Title2, it will contain the answer from Title1Title1.
