Tacho saying I need 24hr break?

It’s in daf 2017. The tacho usualy says what break I need and how much driving I’ve got left. I’m a
Tramper and it’s my 4th day and I used 3 reduced rest so I expected it to say I need 11 hours off but it’s saying 24?

I had 3 days rest prior also

Anyone else had this?

It’s impossible to know what has happened without knowing the detail.
One thing to bear in mind is that the 11 hours has to be within 24 hours of when you started the shift. Effectively this means that if you go over 13 hours total shift including breaks, it is impossible to take 11 hours rest in the 24 hour period. In this case it might be saying that you need to reset by taking a weekly rest.
I would not worry too much. Get it checked out on a download and know the next time.
