[BUG] hit reported at 100% but is completely different

[bifidoman]

Describe the bug
Hi
I run RGI locally v5.2.1 (Ubuntu 22.04)
Database Version CARD:
card_canonical: 3.2.5

Input
I ran standard setting (rgi main -i file -o ./rgi_out/file --local;

Input
assembled genome

I got a hit with 100% identity:
Best_Hit_ARO Best_Identities ARO Model_type SNPs_in_Best_Hit_ARO Other_SNPs
AMR Gene GRD33-1 100 3006926 protein homolog model n/a n/a carbapenem antibiotic inactivation

These are the proteins:

There is not a 100 identity, not even over > 3 AA.
Why is this a hit at 100%?
