Error when taking the Fundamentals On Demand [Japanese] course

[rt_kaneko]

I can expand the Fundamentals On Demand [Japanese] course, but I cannot expand each module, so I cannot study the materials.
I don't know why, but the width of the header menu has also been reduced.
I tried clearing my cache and uninstalling the browser I was using, but it didn't solve the problem.
If anyone knows the cause or solution, please let me know.

Do create a now learning case so it can be resolved -

Please make sure if you can expand menu when you click each module area like 'モジュール1〜' in left menu.

Even if you cannot expand, please confirm what kind of browser do you use like google chrome, edge. I checked administorator fundamental in japanese with google chrome of iOS and then I can expand content menu.

So, if you use google chrome, please set browser zoom rate to 100%(default) or guest mode of browser.
