For range charts, make sure you have "Tick size" set properly for your symbol. Display the Symbol information window (Symbol->Information...), scroll down to Contract Specification and make sure "Tick Size" is set to 0.5 for the FTSE.
The time displayed for a bar can be configured in Tools->Preferences... Go to the Intraday tab and choose how you want compressed bar timestamps displayed. Also, you can use the Custom N-tick/N-volume/range chart settings to create a few default range chart timeframes that you can access by right clicking on a chart and selecting Intraday-><your custom range>.
Tick data works the best for range charts. Anything else usually results in varying range bar sizes.

David
