When using JOINs it is good to name the cattle and not to use *, as this can bring double information and confusion as you doubt it.

I imagine that in your Result you should have two ST and ST1 fields because SQL will rename when you find more than one field with the same name

I saw that you have the Company check in joins, ideally would be put in the Where they are checking the main table "configuration"

That way select select would look something like this

sql = "SELECT b.st, 'outros campos'   FROM configuracao b   
LEFT JOIN dividas a on (b.registro = a.registro)  
left JOIN registros r on (b.registro = r.registro)
where  (b.empresa='" & Left(Combo1.Text, 2) & "')
ORDER BY r.data"

See that I'm bringing the ST of table B and not of R
