Unable to swap stFuel tokens

I had this bug while trying to swap stFuel to Fuel tokens, i had it of recent too on Mira before the relaunch, i thought it would have been fixed, I`m trying to swap 18k stFuel tokens to Fuel tokens to aggregate to the same amount, so i can lock for liquidity. or has the swap function for stFuel token been stopped?, because i previously swapped almost same amount last 2 month or last month and it worked perfectly.
I think an option to lock only stFuel tokens should be provided too, to earn points at the same time and test the product.
Also wen add the dark mode feature?
