Was the TA measured using 10ml or 25ml? If 10ml your precision is only 25ppm so it is not odd that it reports as 275.
Also there is no need to measure the TA every day in my opinion. You should measure at least every few days while you are working on lowering TA to see progress but if you measure daily you may feel like you aren't making progress. pH is more of a daily thing - particularly while you are lowering TA.
It was done using 10 ml. And I stopped testing it everyday. I figured every couple of days test that. My ph came back up to 7.8 and TA. At last test was 250
