what is going on with my salt level?

Hello, I have installed my new AquaRite system in my pool.

I have added correct salt level to the water and my salt sticks indicates about 6 (2800 ppm).

Since start, my system LCD display keep showing the value of 4300-4100 average salt level…I have tried reset it (power on, wait for click, move 5 times to the instant salt) but there are no “moving numbers to select from”, but costant numbers…

I realy dont knwo what to do, any help would be much apprichiated…
