When I use the question type "Drag and drop into text", under certain conditions it doesn't show all the answers.
This happens when I use the same placeholder twice together with the infinite setting:
The 1 barks.
The 2 meows.
The 1 bites.
When you replace the third gap, with a different expression, then everything works as expected.
Has anybody come across the same behaviour? Either there is a problem with the question type or an interference with some other plugins.
