Splitters and modem power levels
Recommended downstream power levels are -7 dbmv to +7 dbmv
Recommended upstream power levels are 35 dbmv to 49 dbmv (Modem manufacturer, Arris, recommends 45 dbmv to 51 dbmv)

First, a manufacturer doesn't provide the acceptable ranges of signal strength for your particular plan and device. Only Cox provides these ranges. If Arris provides one range and Cox another, you must refer to Cox.
With the second splitter installed, you definitely lose downstream power by...what appears...an average of 4 dBmV and upstream by -3.6 dBmV. However, I don't see any significant loss to your SNR. Did you reset your error correction between swaps?
If you're concern with power levels, keep the second splitter off. Why'd you install it?
Well i lost downstream power and gained upstream power. Was trying to center everything
