Fill in the blanks - non-unique id for blanks

Hello,

I'm using h5p on my WP website.

My quizzes are in Turkish, a language which has special characters like ç, ö, ü. So, I integrated a jQuery plugin showing an additional keyboard next to blanks. (H5P doesn't have this feature. I'd love you to add this in one of the next updates) 

However, it doesn't work properly because all the blanks in the quiz have the same id. 

Were there an automatic update from H5P because it was working well before? How can I solve this problem? Is it a matter of couple of change or do I need to hire a developer. What do you think?

Thank you so much.

This is the jQuery plugin I used: https://www.codehim.com/text-input/insert-special-characters-in-textbox-jquery/
