CUSTOM CSS NOT SHOWING CORRECTLY ON EDIT PAGE

When I go to Design > Custom CSS my CSS shows correctly but when I go back to edit the page, it goes back to the default CSS.

MY CSS ON "CUSTOM CSS":

#block-7c548004086f300cf7f2.sqs-block.sqs-background-enabled {
  padding: 8% 6% 5% 6%;
}

Try using !important, if it doesn't work, please share link to page in screenshot, we can check easier

#block-7c548004086f300cf7f2.sqs-block.sqs-background-enabled {
  padding: 8% 6% 5% 6% !important;
}
