Problem with WP Courseware after updates

Hi, I absolutely love loco translate!! I used it on my site with great pleasure, thanks for that ??

There have been many updates lately (WordPress, Divi theme, many plugins) and after the last update of Loco Translate, Loco Translate suddenly cannot find the translations files anymore:

No translations found for “wp-courseware”

I followed the instructions on the wp courseware website before for making a translation, which worked fine before:

‘Don’t forget to change the prefix (text domain) of your mo/po file to “wp_courseware-” for example wp_courseware-de_DE.po & wp_courseware-de_DE.mo.

Lastly, you can store your language file in the /wp-content/languages/wp_courseware/ folder. If you don’t see a languages folder inside of the wp-content folder, simply create one. This will prevent your language file from being overwritten when you update the plugin.‘

I can probably fix this in the ‘Advanced Configuration’Tab, but I don’t know how.

These are the current settings:
text domain: wp-courseware
file prefix: wp-courseware-nl_NL
template file: languages/default.pot
domain path: Include: languages
source file paths: Include: public_html/trainingen/wp-content/languages/wp_courseware

I hope you can help, thanks!!
