Bugs in content types

Hi - On a Mac laptop pro in the latest version of Mojave I have created a drag n drop exercise and created correct coordinated drop zones and labels for the drop zones. I have specified that each text label will have one drop zone. However, when I play the activity in Moodle, when I answer correctly and place the labels where they belong, the results show of all of my answers are incorrect with red text and a -1x. Is this a bug or have I possibly missed a setting in one of the set up menus?

Thanks -

 В интерактивной книге, которую мы создали, очень много искажений исходного текста:замена слов, пропуск целых фрагментов и отдельных слов.  Пробовали редактировать. Исправили ошибки. Сохранили исправленный текст. Ошибки остались! Читать невозможно.

Hi folks,

my interactive video behaves unexpected in the type "single choice set", I adjusted that the video can´t be continued without full points

but the students can continue...this error doesn´t occur in other question types as multiple choice with the same adjustment ("video can´t be continued without full points").

Does anyone have an explanation or has anyone made the same expierience?

kind regards
