rounded corners do not install

[Nuc1eoN]

Hi, thank you for your theme.

I have installed it using the provided install.sh with --tweaks round.
The script then installs the theme successfully with the round version (according to the output).

But in reality my window borders are square after selecting the theme. I am on xfce 4.18 on manjaro. Using xfce's built-in compositor.

EDIT: Tried both release version and latest master
