6hr break rule?

Bloody WTD!!! This is for a Thursday night which is my last shift of week (sun-thurs)

Start: 17:19
End: 23:46
Had 23mins break after approx 2hrs, drove back to our yard, truck on bay, tacho on break for a 15, walked to smoke area, went in for a whiz, grabbed a coffee, quick chat & back to truck to change mode to ‘other work’ and complete my paperwork…now, turns out I only had 14 mins second break (must have miscounted the mins) in the 6hrs 27m I was on duty before pulling card until 18:00 Sunday evening…Oh well!
