Are all NVMe drives suffering from this write cache issue? Is it even an issue? Any fix for it? Disable write cache in windows helps or hurts performance? I posted this chart another Hardforum member posted I forgot who it was credit to that member but I wanted to understand if there is a solution or not.

No, it's not an issue in virtually any real-life usage. It's simply a benchmark that details when and what happens when the SSD's cache fills up.

The write rate that most of those SSDs drop to when the cache is full (~1200-1800 MB/s) is still 2-3x that of SATA3 (max ~550 MB/s real-world) and as much as half that of PCIe3 (~3500 MB/s real-world).
