Filelight on kde shows a wrong directory

Hi, I notice that the filelight app on my machine (endeavour with kde), shows another home directory, with the same name of my home directory, but of a much smaller size. (i.e. I have 2 /home/yuanhao/ in the filelight app under /, one is correct, anther one is very small size)


I have tried rescan, and reinstall, did not help.
what’s wrong with the app and how to fix?

Is it possible you mounted the larger one over the smaller one?

What does findmnt --real show?

it shows this

[yuanhao@yh-G14-GA402RK ~]$ findmnt --real
