Hi team, I’m using

airbyte 0.40.3

with a

MySQL

source of version

0.6.5

, and my source table has a primary key and an

updated_at

field which can be set as a cursor field. but I can’t choose

incremental sync Deduplicate history

sync mode. according the doc, it seems that I am able to use the

deduplicate history

sync mode, so I’m wondering if there are something I missed?
