Warning! SMART Attribute Thresholds Structure error: invalid SMART checksum

I purchased a new WD Red Plus from Amazon and received this warning. Returned and bought another direct from Western Digital and received the same warning on the 2nd drive. The WD Red Plus that I have from a year ago does not receive this warning, so I suspect that WD made a change to the firmware

Here’s the smartctl info:

I realize that this is just a warning and as a long test completes without error I can just ignore it, but still thought this was worth a ticket
