Groups in Designer?

While compiling the questionnaire in designer, you can get this prompt:

[WB0232]:Five or more questions have the same enabling condition. Place questions in a group and apply single enabling condition to a group to improve questionnaire efficiency.

What are groups? Was it supposed to be Sub-section?

Yes indeed, ‘group’ objects were renamed as ‘sub-section’ but unfortunately there are still literals left that refer to the old name…
