Multiple slides with text on stage screen only

I would be happy to help you. Insert your text the same as normal via insert text, but once you get the cue built, then click into the text box on the main side, and go to the FX button in the ribbon bar, and take the opacity down to "1" instead of "100." This will make it invisible on the main screen, but will still show on the stage screen. Plus you can even put a graphic or video as the background, so there's at least an image on the front screen while the folks see the text on the stage screen. You'll just want to do any editing of the text as far as page breaks, splitting, etc, on the main side still, and the stage screen will follow suit. It may show the text as being invisible, but if you click your cursor in where the text box should be, you'll see it populate with the "invisible" text for editing.

It is possible you just need to go to one of the pages that the text IS invisible, click into the text box, and click Apply to Cue to ensure that "1" value is applied to all pages. But if that doesn't work, it probably means that text box on page 1 is not connected to the rest of the text for instance. That means it is its own text box separate from the other. So you can just click into the text on page 1, and do the FX button to apply the "1" value to it as well. Let us know if you need more help.
