Java Preview Issues with Win 10

I am a mentor for a First Robotics Team. In First, high schools students design, build and program a robot in Java. The robot is used in competitions against other teams. I am using Codecadamy to teach the group of students JAVA. It is a great resource and I have 10 students progressing through your new Java class. The website works quite well with one exception. One of my students has his own computer using windows-10 and is experiencing the following: All text appears to be right justified on all your web pages. This does not happen with any other sites. The behavior is the same on Edge, Chrome and Firefox. I tried erasing all browsing history and that did not change anything. Do you have any recommendations?

Could you post a screen shot of that please?
