Zwift free ride question

During a workout, there was an section for “free ride” which, I thought meant ride freely. However, there was instructions every few minutes that stated to change cadence, etc. there were also numbers that didn’t make much sense, unsure if they are simply tips or truly what I was supposed to be doing.

Ordinarily during a free ride it means that, no targets etc… Just time to do what you want.
Can you screenshot the workout on the selection page and it should show what targets were set.
