"Missing word" import type only works with missing word, not MC as help says

The Missing Word format is show as an import file type in both Question bank and Lesson. The help screen says depending upon the number of answers in the { } will determine if it is a short answer or a Multiple Choice question.

In demo.moodle.net, I tried importing a UTF-8 text file with the example given in help. It gave me an error. Here are the two examples given. The first does not work in Lesson nor Question bank. The second works in both.

As soon as we begin to explore our body parts as infants we become students of

{=anatomy and physiology ~reflexology ~science ~experiment}

Seems sort of silly to have a 1 function question import. Perhaps we should drop it? I was working on the[[ Import questions]] page in docs.moodle and created [[Missing word question format]]. Can I have an example of the MC type in this format that works? Thanks Chris
