Seen this before, and as a guy with broad experience in databases, the answer can be found in how this system handles its databases.
The product description is a result of the product code. 902780=Covid-19 diagnosis test…
If you have a direct correlation between the production code and the production description, the description will change also for historical queries.
If the description was changed from (let’s say) “flu diagnosis test instruments and apparatus” to “Covid-19 diagnosis test instruments and apparatus” in 2020, and you go back to do a 2018 query using the updated 2020 product description, you’ll get results like this.
I’m not saying this is the case here, but it’s a very plausible explanation.

So this is saying covid is the flu. Got it.
