Hi
I made a Fill in the Blanks and the Attemps Report is not correct.
I use H5P Core and I think it's a Moodle problem: in H5P Core not in H5P plugin.
I posted on the H5P forum for more information, because I can't test on H5P plugin.

This is the H5P I used for the test https://h5p.org/sites/default/files/Case%20Sensitive.h5p
This problem looks very similar to https://tracker.moodle.org/browse/MDL-77197
I think it are both uppercase/lowercase coding-problems.
