RODI reading 3 ppm

[Exotrezy]

Hey guys, I need some help. My tds was reading 2 ppm so l replaced my di, after I replaced it, it read 3 ppm, and then I replaced my RO sediment, and both carbon filters and It is still reading 3.
I am assuming I replaced the di wrong?
I have let it run for about 7 gallons so far btw and still showing 3 ppm
it was showing 0 ppm btw a few weeks ago before it showed 2 ppm suddenly. Any advice?

Update: turns out I installed the DI plastic thingy that holds the beads upside down so I just flipped it the right way, so let me run the water for a little bit more and see if that fixed it.
