When you have a multi-column layout (add question to same row) and a question event that unhides more questions in subsequent sections, singleline text boxes are getting 'converted' (displayed) as multilinetext boxes as the hidden questions appear.
For instance if you start with a basic layout like:
Question 1:
Question 4:
|
Question 2:
Question 5
|
Question 3:
Question 6:
|
When question 4 is selected and it unhides question 5 and 6, questions 2 and 3 get changed during the event and the result page now looks like:
Question 1:
Question 4:
|
Question 2:
Single Text (box expands to multiline).
|
Question 5:
|
Question 3:
Single Text (box expands to multiline).
|
Question 6:
