Disk space counted twice on root folder?

Edit: SOLVED thanks to r00ty !

Hello, I have this weird issue that my Debian 11 will tell me the root folder is full, while I can only find files for half of the accounted space.

df -h reports 56G while the disk analyser (sudo baobab) only finds 28G.

Anyone ever encountered this? I don't have anything mounted twice.... (Not sure what udev is). Also it does not add up to 100%, it should say 7.2G left not 4.1G

df -h /dev/sda* Filesystem Size Used Avail Use% Mounted on udev 16G 0 16G 0% /dev /dev/sda1 511M 22M 490M 5% /boot/efi /dev/sda2 63G 56G 4.1G 94% / /dev/sda4 852G 386G 423G 48% /home

Edit: my mtab

Edit 2: what Gparted shows

What does `lsblk -f say?

lsblk -f NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINT sda
├─sda1 │ vfat FAT32 7DA7-E2FD 489.1M 4% /boot/efi ├─sda2 │ ext4 1.0 c3f96c3b-37d7-439d-abab-103714f5d047 4G 88% / ├─sda3 │ swap 1 swap 1f3122c8-f4ec-4596-a767-2126d8ff90d9

This one shows 88% full, which seems more like what Gparted shows. But still no clue why 2x28GB is shown

Exactly try to execute lsblk -f and look at your sda (sda2).
