fridgidaire water inlet valve leaking

I have Fridgidaire FRS6LF7FQ6 and the water inlet valve was leaking. I replaced it (AP03160649) and the new valve has new quick connect fittings, which are much easier…except I cant get them to stop leaking. I have double and triple checked that the cuts I made to the plastic tubes are clean and straight. Connections appear to be fine, but continue to leak ( a lot ) when the water dispenser is pressed.

Any ideas?
