A few weeks ago I put new strings on my guitar, befor I put the new strings onto my guitar, I cleaned and waxed it. While I turned the guitar over to clean the back side, the saddle fell out, (the long part forward of the bridge, that lifts the strings up). Not knowingly I put it in back wards,the highest end must be holding up the thicker strings and the lowest end should be holding up the thinner strings. I could not understand that my guitar tuner was acting strangly lately. I found out lately on the internet, that having that long bar backwards will effect the tuner.
