Web/HTML 5 Publish

Hi everybody. I just created a portfolio using Storyline. I published as Web and since I used the Modern Player I published in HTML 5.

The entire size of the project is 21mb. When the project is viewed via a mobile device it loads very slowly,  a lot slower than a computer. First I thought it was my network but I had tested on different networks and the results are the same. It also behaves a bit erratic, for example when you zoom in, and for some reason a video that I muted the sound in storyline it sometimes turns on. Never happens on a computer. I started looking at the files and I noticed that the Mobile folder includes a lot of the same files with a different name. Here's a screenshot of the folder.

Any ideas why this is happenning?

Thank you for your help in advance.
