Loss Made 2020-21 How To Use Now??

I made a loss on one off my self employed businesses in 2020-21 of 7153.00 but I am finding it difficult to use it against my 108620 profit I have on my current 2022-23 submission I am working on. Anybody know how I can use this on these accounts please as every time I type it in the "Loss brought forward from earlier years set-off against 2022-23 profits" section, it recalculates the 10862 to 3709 then resets once I've clicked continue!?!

Hi B,
As you have brought forward the losses, the £3709 is the correct revised profit - 10682 minus 7153.
Thank you.
