Cannot convert 2486S 6-button to 8-button

So this is the switch model not the dimmer and I believe it's the older model - not the 2334 type of 6 button. I tried putting an 8 panel on it, plugged in, pull out set button 10s, hold Main and H simultaneously while pushing the set button in and holding. It still comes up as a six panel. I'm wondering if these older models cannot be swapped.

I spoke too soon. I was holding Main and H buttons and the pushing in "and holding in" the set button for about 10s.

The correct way is to: Pull set button out. Hold Main and H but just push the set button back in flush - do not push it in and hold it as if it was a hard reset. But do hold Main and H for 3 seconds and then release Main and H - set button should have already been released (since you never hold it in.)
