when i open the home folder (home.desktop) and trash folder from the desktop it opens it in nemo file manager(cinnamon's file manager) instead of dolphin in my KDE plasma5.

If i try to create new folder on desktop it creates it like this:


And if i click "open with" option from top left corner or by right clicking in desktop i don't get the plasma right click menu after.
Trying right click anywhere in the desktop after that looks like this


The applications default i set to dolphin only for file manager. I have installed cinnamon,xfce,enlightenment DE along with my KDE plasma5.
