Why am I prompted for my password every time I access a mounted disk under 20.04?

I have several SSD disks connected on my Ubuntu server, and under 19.10, they were mounted automatically under their respective directories. But under 20.04, every time I want to access one, it asks me for my password. It shows "administrator" in the file manager. Also the file system in the shortcuts in "other locations" all show like it is a network drive.

I have the following when I type the mount command:

/dev/sda1 on /vm type ext4 (rw,nosuid,nodev,relatime)/dev/sdc1 on /data2 type ext4 (rw,nosuid,nodev,relatime)/dev/sdd1 on /data type ext4 (rw,nosuid,nodev,relatime)/dev/sdd2 on /ISO type ext4 (rw,nosuid,nodev,relatime)

And I have the following under /etc/fstab:

# /ISO was on /dev/sdd2 during installationUUID=fb4ab474-a5a7-4226-8f91-80d9e9278fc7 /ISO            ext4    defaults,owner   0       2# /data was on /dev/sdd1 during installationUUID=f0492204-e674-475d-84af-72e59454af3c /data           ext4    defaults,owner   0       2# /data2 was on /dev/sdc1 during installationUUID=5572ea43-44dc-45d8-b5ec-942cfb4916c9 /data2          ext4    defaults,owner   0       2# /vm was on /dev/sda1 during installationUUID=c66fbf3d-76f6-4072-884a-eb440623ed40 /vm             ext4    defaults,owner   0       2

I made sure my newly created username is the owner of the whole disks and has rw rights.
