explain result different in different versions

hi admin

firstly, my function runs well in 10.3 10.5 and 10.6. But when I upgrade database to 10.7.6 10.8.5 10.9.2 (fresh install, and then restore the database), I meet same questions that the query takes long time, and use explain to analysis, I found out that the SQL run sequence is not from From table anymore. here is the screenshot, may I know whether there are changes I should configure.

explain in 10.6.10 is explain_in_10_6_10

explain in 10.9.2 is explain_in_10_9_2
