Master/Detail Sample not working

I deployed Sample Project enclosed with SC8 - on line. When trying Master/Detail App discovered that the record scrolling (left/right arrow) does not work.
The app seems to go into the loop and never downloads the next record in sequence. Any ideas ?

Maybe the plugin of CMS is not compatible.

No, I test it inside CMS and outside and it doesn’t work either way.
