OBD Report - Then and Now. Does anything jump out at you?

Attached are two freeze-frames from my ML320. One is from November, 2018 and the other is from today, July 1, 2019.
In that time, I've replaced the mass airflow sensor: Bosch Original Equipment 0280217515, an o2 sensor: Bosch 16276 Oxygen Sensor, Original Equipment, and a crankshaft position sensor: Bosch Original Equipment 0261210170 Crankshaft Position Sensor, all based on codes I've received. The codes have seemingly minimized except that darn MAF.
Attached are OBD reports from last November and today. Admittedly, I don't know much about what I'm presenting but does anything jump out at you?
Thank you in advance,
Sam

Misfiring on left bank.
Check your ignition coils and spark plug wires.

Maybe the CATs are shot.
