RO system has high TDS after filter replaced

I have a 5 stage RO system that I replaced the filters 2 weeks ago. Ever since the replacement, the water just tastes salty compared to how it was before. I even tried to taste my tap water. Ironically, it is actually not as salty as my drinking water that filtered thru the RO system. Using the TDS meter, I got 107 from tap water. RO system is 200. Old water sample before RO filter replacement is 78. I tried to turn off the pressure tank and the water TDS runs at 134. What am I doing it wrong here? I even tried to drain out all the water in the pressure tank. But after the tank is filled again, the water sample still runs at 215.

This is my first time replace the filters. Did I screw something up? I replaced all the filters except membrane filter. Before then, I always have the company come to replace the filters for me. They charge me around 230 or so each year and the membrane filter was not replaced since 2010.

What should I do now?
