1099-R possibly incorrect

I take RMDs from an old 401k plan. Normally I receive a 1099-R listing the amount in Box 1 Gross Distribution and Box 2a Taxable amount. No boxes are checked. For 2024, I took my RMD as usual and the former employer moved the 401k to a new administrator at year end. I received the 1099-R with box 1 and 2a listing the RMD amount. However, the Total Distribution box was checked. IMHO, the box should not be checked because it does not relate to the amount in Box 1. I called the old administrator who checked with the “back office”. They say the box was checked because the account balance was 0 at year end.
