Fill in the Blanks

Does anyone know how to remove the blue band that now appears at the top of any new content that I make? For example here: https://h5p.org/node/727542

Hello,

I am getting error with code 500 and 406 while I run the quiz, especially the fill ups and drag the text type.
Error screenshot is attached herewith. Sometimes this error do not appear.

hello,

can anyone confirm that fill in the blanks works for a retry after the first incorrect answer?
After filling in some wrong text one cannot enter a second time as retry.
Please check here, third question for direct navigation.

put filed on seperate lines

Adaptivity:
Require full score for task before proceeding

any ideas how to get h5p accept the second, third, ... try?
