Bugs in content types

In some cases a feedback line appears for a multiple choice question (independent of whether there is any feedback content created). In other cases feedback does not appear. When the alternative is deleted and created again, the feedback disappears. Question: when does the feedback appear and when not. Is there a control for this?

When retry is clicked on the Summary page, the user is moved to the first slide. Score is set to 0% again. The previously chosen answer is presented and the user clicks on Check. However, the question is not scored again. Only when an incorrect answer is chosen first and then the correct answer (actually clicking in the question itself) the answer is scored.

This is confusing and leads to many retries with low scores.

See the attached example quiz and screenshots.

Als when retry is selected the content should send the XAPI statements for the whole quiz.

It's great to have an enhancement of the text editor in the recent release, but there are iissues with selecting text and applying color/background colour/text size. E.g. applying size and colour on the same text is impossible. Also to apply colour and size is counterintuitive compared to the other options (bold/italic). It is not possible to select some text and then change the colour or the font size.
