Custom Page View Option Missing

Since version 2.5 the custom page view option has been missing from Scrivener.

The latest beta version - 2.5.5 Build 25316 - does not restore the feature.

The custom page view option can still be configured in preferences, but cannot be enabled.

It is found in the lower right corner of preferences here:

It should be enable-able from the View - Page View menu, but the option has been gone since the release of 2.5.

Thanks, I already responded to this over in the other thread that you posted in.
