Multiple Choice

Problem with Multiple Choices when I have an arithmetic value in the offered answers.

Respected,

when I try to create a question in the Multiple Choice type, and I have arithmetic values in the attempted answers, WordPress throws out a 404 error.
This only happens when I have an arithmetic value in the offered answers (for example 5 + 2 = 7)

Wordpress 5.7.2
H5P 1.15.2
Chrome Browser
