Does anyone know why, when I pull the squid jigger data for the IATTC area, I get different values than those shown on the map?

For example, for 2011 in the IATTC area, the map shows 210 vessels, while gfwR () results 197 unique vessels.

Here are the <https://globalfishingwatch.org/map/fishing-activity/default-public/report/public-rfmo/IATTC?_gl=1%2A1hg2zn9%2A_gcl_au%2AMTgxODMyMDk4LjE3NTU3OTQyMjU.%2A_ga%2AMjI4MjQyODM3LjE3NTU3OTQyMjU.%2A_ga_5W83X3EYGW%2AczE3NTkzMjM0NDEkbzUyJGcwJHQxNzU5MzIzNDQxJGo2MCRsMCRoNDY0Nzg1MDI4%2A_ga_M5J2ZHDZMV%2AczE3NTkzMjM0NDEkbzE5JGcwJHQxNzU5MzIzNDQxJGo2MCRsMCRoOTI5MDUzOTM3&amp;longitude=-110.02665&amp;latitude=0&amp;zoom=1.92618414&amp;dvIn[0][id]=context-layer-rfmo&amp;dvIn[0][cfg][vis]=true&amp;dvIn[1][id]=vms&amp;dvIn[1][cfg][vis]=false&amp;dvIn[2][id]=ais&amp;dvIn[2][cfg][vis]=true&amp;dvIn[2][cfg][filters][geartype][0]=squid_jigger&amp;bDV&amp;start=2021-01-01T00%3A00%3A00.000Z&amp;end=2022-01-01T00%3A00%3A00.000Z&amp;lTD=&amp;fTD=&amp;trackCorrectionId=&amp;aVM=heatmap|dynamic report> and code.
