Switching between BS6700 & BS EN 806. Loading units do not change automatically?

When pipe sizing using NetsSYS I have created a project and I am interested in the differences in flow rates, pipe sizes etc between BS 6700 & BS EN 806... If i change the sizing method on defaults, it does not automatically change the loading units to all outlets, which can be viewed by selecting 'change outlets'. Is there any way to force the software to update the loading units at all outlets?

Thanks
