I have a Samsumg 970 EVO Plus I use for my system. I recently checked the drive with nvme smart-log but I'm not getting output (this has functioned properly before)

I run the same with smartctl and I'm getting proper output.

Any idea why the smart-log is not producing output yet smartctl does in which according to it that the drive is fine?
Also I measured the performance of the drive with hdparm -Tt --direct and compared it with my other drive a regular Samsung 970 EVO and surprisingly the regular EVO performs better than the EVO Plus. For reading the Plus registers 1283.41 MB/sec but the regular EVO clocks much higher at 1836.59 MB/sec. This makes me feel there's something wrong with the EVO Pro.
Am I in need of a firmware update? I tried to find a firmware update for the Samsung drive. There's no link in the wiki and Samsung's magician in the AUR repo is outdated. Please share if you have a way of updating EVO firmware.
