Issues with Multi-tabbed Notebook Powerpoint Presentation imported into Storyline 2

I customised Tom's multi-colored tabs template for Powerpoint and imported the presentation into Storyline 2.

Issues/Questions:

• There are hyperlinks on most slides to advance to the next slide and back to the previous slide, they worked perfectly in Powerpoint, but now the 'back to previous slide' hyperlinks on the notebook pagesdon't work while those on the notebook cover pages do work.
• The text boxes now overflow the slide/tab, where they were perfectly placed/sized in Powerpoint

This is a small sample module for a series of 10 modules to be completed so I need to get things right before continuing with the presentations to eliminate as much fiddling with the Storyline files as possible.  Any suggestions/thoughts are greatly appreciated.

Thanks!
