Yikes, they also didn't put NZL and DEN in the right category in Women's K1 500m, those are only boat quotas.
I think BLR in Men's K1 1000m has to get the CZE reallocation quota regardless of how the host quota works, because the "double up" reallocation supposed to happen before the host quota reallocation.
Anyway, Argentina is likely getting the quota, because the note says "relevant category", which I am assuming means that host quota works similarly to the 2016 system.
