Record audio macro help

I recently re-formatted my hdd and successfully installed Cubase 6 and vst instruments.

Set up my usual macros but am having trouble with my record macro .

From memory it was
use pre-roll
use pre-roll

Have set pre-roll and post-roll to 1 bar and assigned macro to V on the key board.

However…when i try to record it goes back 1 bar then enters record at left locator but carrys on recording past right locator

Can anybody help please

Surely someone can help please
