style.css not applying (twenty twenty)

Hello, I have been deleting some lines off the style.CSS and I noticed that nothing changed (the live css customisation tool works fine), I looked at the chrome inspector and saw that the lines I deleted where still here at the lines indicated before I deleted them, I checked on the FTP and the lines were deleted, the lines are here on every browser even tho I cleared the cache, the lines are still there in inconito mode, if anyone has a solution, please help me

The lines i seek to delete are :

.primary-menu-wrapper {
display: none;
} (line 1569)

.header-navigation-wrapper {
display: none;
} (line 1472)
