Stoneridge tacho issues

I just looked at tonights 24hr print out and its saying i have only 7.45 hrs rest since card was last ejected at 18:05 on 16-11-18 how has this happened as wen i got in the truck this morning it asked had i been on rest since last ejected i just selected yes and carried on ■■ Should i have put in a manual entry and is there still time to put in a manual entry the next time i put my card in or can manual entry only be done the 1st time you enter the card since it was last ejected ■■

and if it is an infringement is there a time frame that the infringement expires, if i dont get stopped with vosa in so many days will the infringement be wiped ■■
