Easel not adding tabs

I’m having a bit of an issue adding tabs. I will click the add tabs and move them to the appropriate place on my design. However, my issue seems to be that the tabs are not added to the detailed preview or the final cut. What am I doing wrong?

Hello Sarah and welcome to the forum,
You will not see the tabs in the detailed preview window but they should be in the cut. Are you sure you’re not cutting them off?
Do you notice if the router goes up and down in certain spots?
