Bugfix CustomView selection during dive mode: The CustomView selection during dive mode was limited to two pages, while meanwhile three are needed to show all options. The problem did not showup in surface mode selection. Rootcause was a static definition instead of the dynamic one used in surface mode. In addition with every page shift a new page was created which might cause display errors after some times. To solve this the pages are now updated instead of rebuilding the pages.
