Hello - 

We have our training material setup in a way that users do not need to complete each one for the course to mark complete (various language options).

However, a progress bar and X/X lessons completed appears in the course player, that we thought would be confusing to the end user. 

We used the following CSS to hide both of these elements. Please feel free to use the code as well.

/* Remove Course Player Lessons Progress Bar */

.progress-bar.bg-grey {
    display: none! important;
}

/* Hide X Lessons Completed on Course Player */

.subtitle-block {
    display: none! important;
}
