The step to as one can see was in bold display,so the crew must have input fl390S on the legs page.Usually if the FMS is allowed to calculate the step climb it does not present it in bold display
I agree for what it's worth, 390S has been entered and it is telling you that you have 68 nm to go to a "forced" step.
OPT and Max show the current values for the weight.
Seen it when I get a particular crossing altitude for the tracks for which I did not really want, but got it anyway.
