My first knee-jerk reaction is:
Rule of thumb - One amplifier can be too many. Two amplifiers are too many.
What happens when you remove all amplifiers... connect one TV to the 'bare-foot' antenna feed? (I would expect the CS2 to deliver enough signal power with no amplifier needed... except for WLUK.)
Does the CS2 face NE?
The CS2 is a UHF only design, WLUK is broadcast on real channel 11 (VHF). You may need a high-VHF antenna such as an Antennacraft Y5713 and a
UVSJ to combine your existing UHF and the additional VHF signals. Try removing the amplifiers first.
