Filling wrong category

I applied for the Rsmssb Stenographer post in 2018..there I filled my category general instead of obc non creamy layer because I had a misconception that I belong from obc creamy layer due to 8 lakh per year family income..later the Rsmssb gave edit option two times in 2020 and 2021 before the first phase exam but I did not notice..later when I came to know about my actual obc non creamy layer category I applied for my certificate and I got it on 1st Nov 2021 and the just one day before on 31st Oct 2021 I had my second phase exam..after getting my certificate I went to the board office with affidavit and certificate to notify my mistake but they said there is nothing can be happen now and if you get selected then you can submit these affidavit and certificate at the time of your document verification..later board passd 2300 students for the 1211 posts for document verification..I gave those documents but they said nothing can be happen your category cant be changed..I had 240 marks and the document verification cut off for general is 238 and 229 for obc..I want to ask if there is any chance of considering me in obc non creamy layer challenging in the court this case because final result is not out yet and no one is getting hurt by this pleaf obc non creamy layer
