I'm sorry to hear that you're experiencing this, and I'm here to help you resolve it.
Those credits got stuck.
So, please let me explain.
An automatic translation account ID is created when installing and setting up WPML.
If you uninstall/reset WPML or reinstall/set WordPress from scratch, a new automatic translation account ID will be generated, and the credits will remain in the old account.
I found the credits on the older account and moved them to your current account.
You should see them on the site now if you go to WPML > Translation Management > Tools (in the top-left area).
Can you please confirm that you can see the credits in the backend of your site?
