Bugs in content types

Hi. I'm trying to get mathematical expressions in H5P installed in Moodle. Following the instructions that I got in several sites (specially https://h5p.org/mathematical-expressions), I install the math display library in my Moodle site sucessfully. Even more, I did the same in Lumio and there it works. Nevertheless, in my Moodle site, I'm unable to get the same result of Lumio. 

My Moodle site runs version 4.15

Thanks a lot for your valuable advices.
