475 MTM elected trader 1099 misc wash sales

I qualify and elected for 475 MTM 2 years ago and changed my accounting when i filed my taxes in 2023. My question is, I called Fidelity my broker and although I submitted a wash sales suppression form because I am MTM, they keep showing wash sales in my 1099 misc. When I called them, they said they're not supposed to suppress wash sales from short sales.

 

Is this true? I thought MTM meant that "traders who make the Sec. 475(f) election are deemed to have sold all their stocks and securities for their FMV on the last business day of the tax year. In other words, every position in the trader’s trading account is marked to market and is deemed to be sold at that price at the end of each year. As a result, traders must recognize all gains and losses on the constructive sales as of that date."

 

does this not account for short sales?
