Page not working

Hi ! I am testing my app on the new engine (IB4.0). Everything seems to work well (appart from the global elements not showing on the Design Mode; but apparently working on Player) but when I arrive to page 11; then nothing works! I have only "Jump to page" behaviours on that page (and some fade in behaviours), that are triggered tapping on empty graphic objects (invisible objects) put on top of other graphics. The same structure works fine on other pages, but strangely, on that specific page they don't work at all, not even the "go to previous / next page" behaviour!

I can't imagine why... please, could you check it?

Thanks
Pablo
