Codes appeared at the top of the screen

Hello

We exported the course in the format of AICC, and then uploaded to the LMS. The following two problems appeared when we watched the course through Safari on iPad. Due to the provisions of the company, we had to watch directly through Safari, not APP.
 
1. When the iPad was turned to vertical screen, codes appeared at the top of the screen, please see the picture, I would like to ask how to remove these codes.

 
2. When we opened the course through the computer, if 10% of the original course was learned, after logging in next time, learning would be continued from where was not learned last time. However, if we watched the course on the iPad, we found this function could not be realized. After each time of logging in, we had to learn from the beginning and could not continue to learn from where was not learned last time. May I ask how to solve this problem? If the course was not uploaded to the LMS but just uploaded to the website, there would be the function of recording, we could continue to learn from where was not learned. However, if the course was uploaded to the LMS platform, the problem above would appear.
