Issue with new Spectra Select

I ordered a new spectra select 90 gpd membrane through Premium Aquatics.
I'm about 100 gallons of water through the membrane. Have run 3 cycles, each about 30 gallons. 235ppm (+/-) tds going into the filter, and still getting 12-14ppm tds after the membrane, both at startup and hours into the water run. The water from the spectraselect I replaced was consistently 1-2ppm at startup, and somewhere between 4-7 ppm after running for a few hours (depending on the tap water temperature).
I checked the membrane, it seems to be fully seated.
This is my third Spectra Select membrane, and I've never had this problem before.

What am I missing? Is it possible the membrane has been compromised?
