Drag the Words

Drag the words - Dont appear the Activity


I have a problem with h5p on Moodle 4.1. When i create a Drag the words, its works perfectly, i can create my examples, but when i save and go to the activity, dont load. If i add another activities works fine. 

The error occurs on all browsers and phones. The versión of H5P is 1.23.0 and the version of the Drag the Words (1.10.4)
