The user has a questionnaire and is trying to hide a set of questions. Some are hidden properly, while others are not.
This article explains the purpose of running the DDE Analyzer to see what is triggering, which can be initialized with the Ctrl +Alt-+ Left-Click shortcut.
After running DDE analyzer, it was discovered that a conditional layout that set the question the user was trying to hide was setting it to read-only. Therefore, the conditions were conflicting.
To resolve the issue, an opposite condition was added to the one that was set as read-only so that it would be false when the one to hide was true.
Lesson learned A field cannot be hidden if it is set to read-only, and changing the order will not help as they are conflicting. It is always best to have just one conditional layout trigger as true at a time.
