Crystal Disk Info E8=0 BAD Sandisk Extreme Pro USB

I just got a new SanDisk Extreme Pro USB 3.2 flash drive. All read write tests pass 100% and all sectors are 100% good using various utilities. When I run Crystal Disk Info on the USB SSD flash drive all SMART factors test good except for E8 which equals 0 for spare blocks remaining. Has anyone else seen this error code when the USB flash drive is tested with Crystal Disk Info. Is this brand new drive defective or am I missing something. Drive is 128gb with firmware 6eb1030.

Personally I wouldn’t worry about it. Maybe your Crystal Disk app is out of date.
