Not a bug and not a question but definitely something that should either be added to the Help Guides or fixed..
As I discovered today, if you are doing a multi-part gap fill question eg
And you choose a range of possible answers:
And use the Word bank option
You then get duplicate choices appearing.
These are fine as long as none of the duplicates is the answer.
As what happened in my lesson today (with many students), it then possible for a student to get the right answer eg green but choose the wrong green from the word bank.
It would be really useful if Canvas fixed this as it removes a good feature (word banks) with an important option (multi-part questions)
