Responsive Knowledge Check Bugs _ Captivate 8

Recently when publishing my current responsive project that is in mid-development, I noticed two problems with knowledge checks (quiz) that I'm hoping someone can help me resolve.

First - The feedback messages are inserting a return before the last word of each feedback response and putting the last word on a separate line . I have tried deleting the last word and several words before in an attempt to get rid of some phantom return, but that has not resolved the issue. So, just wondering if anyone else has had this problem and what it took to resolve.

Second - I have not used the matching question type in previous responsive projects, but have two matching questions in this project. When I published the project and reviewed (outside of the LMS), when I got to these questions and clicked the drop down arrow, I discovered that the letters choices do not display. I can guess where "A," "B," and the other letters are in the blank box and "select" them and the letter will populate in the box and a line for the line for the two elements drawn will display, but if my approximation of where each letter choice is located in the drop down is wrong (since they aren't displaying), I - of course - get the wrong letter/line association. So, is this a known issue and are matching question types not possible with the responsive format? Or is this a bug that there is some way for me to fix? If the latter, how do I fix this issue? 

Thanks!
