Swap file create/activated

I have install dietpi through lean debian image after giving script command. everything is working but in htop i am not able to see swap file size. as i already delete swap partition from HDD. so for creating swap file i gave this command

/boot/dietpi/func/dietpi-set_swapfile 4000

after this command i checked system create swap file. also in dietpi-config>advance>

swap file = [3999mb] | /var/swap


but still in HTOP command swap memory not showed. is i have to edit somewhere so that it can work as intended? i have done reboot multiple time after still it not showed up

It showed after some time. so problem solve. please ignore this message. thanks
