LifterLMS translations are maintained by volunteers and contributors so if there are any errors in translation, we cannot fix those. Instead, you should report these errors to the relevant translation contributor or you can suggest a better or correct translation.
For errors in the LifterLMS core, translations can be submitted GlotPress at WordPress.org.
For errors in paid add-ons, you can suggest a new translation via GlotPress at translate.lifterlms.com.
You can read our full translation contributor’s guide at https://lifterlms.com/docs/how-can-i-contribute-translations-to-lifterlms/.
If you’ve found a string which is not translatable please let us know.
