Moving entries in a Robohelp 2019 project - output is HTML5
I have a 2019 RH project (Version .9) for which I have created and ordered a TOC. In this TOC, I have a book entry that has three (3) page/topic entries underneath it all at the same level. I want to move the third of these page/topic entries one more position to the right - i.e., indented one place more to the right underneath the 2nd page entry. I right-click on the 3rd page entry, and on the context menu that opens, I click Move > Right , but nada, zip, zilch. The 3rd page entry stays put. Is there a limit for some bizarre reason on indenting/moving TOC page entries? I have attached a screen shot of what I have and what I want, but can't get!
Thanks!
