Snowflake / dbt DAY_OF_WEEK incorrect

[tuday2]

I am trying to create a date dimension with Snowflake. I need the week to start on Sunday.

I finally figured out I needed to change the Snowflake "WEEK_START" setting to 7 (Sunday) to get week numbers to accurately reflect a Sunday start.

Now the issue is with Day of Week. With Snowflake "WEEK_START" set to 7, here is the output of dbt-date for iso/non-iso:
Sunday = 7 (DAY_OF_WEEK_ISO)
Sunday = 2 (DAY_OF_WEEK)

I need Sunday to be 1. Looking at the code in DAY_OF_WEEK i stumbled upon this line below that is adding + 1 (did Snowflake use to return 0?) -- this is causing Sunday to be 2 in DAY_OF_WEEK which is not correct.

If I run the snowflake functions directly for 01/02/2022, a Sunday, they are correct:
SELECT DAYOFWEEK(date'2022-01-02') = 1
SELECT DAYOFWEEKISO(date'2022-01-02') = 7

So my guess is that +1 in the DAYOFWEEK is not needed anymore.
