An old employer terminated a 401k plan and did a direct rollover to a Roth IRA (90%) and to traditional IRA (10%). 1099R has BG in box 7 for Roth IRA. Should it be H?

The traditional IRA rollover code of G is correct.  The conversion was done in 2023 and I am well past 591/2 years and the 401k was more than 5 years old.  The 401K administrator insists BG code is correct... but I am not sure.
