Simulate bundle problem

Hi everyone.

I am having some trouble with flashbot. I am building a tx and sending it with flashbot, but the weird thing is when I simulate the bundle to check if everything is fine, the gas price I put in my tx is not the same as the simulation one, do you know why? Has anyone experienced this problem too?

BTW, I tested on goerli and everything was fine but now on the mainnet I have this problem.

For example, the gas price in my tx is : 34651289999 wei
But in the bundle simulation i have this: gas_price: 7923

If i check juste after the simulation, the transaction gas price is 34651289999, so is it just a simulation display problem? Or something else?

Thank you very much in advance for your help and have a great day everyone.
