`mount` works, `mount -a` not - same config, two drives

I have two external ext4 SSD drives connected on my Ubuntu 22.04.1 LTS system.

$ blkid.../dev/sda1: LABEL="ext01" UUID="4f384179-5f1d-41b6-9cb0-a9cc1cbc15b4" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="62bb06c9-01"/dev/sdb1: LABEL="ext02" UUID="11f26526-81e1-4095-9d19-f68a81429c5d" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="0ab49ec5-01"

I can mount both drives manually, but ext02 will fail when I use mount -a.
ext01 just works.
Both drives are formatted the same way.

Manually:

$ mount UUID=11f26526-81e1-4095-9d19-f68a81429c5d /media/ext02

Works also when I replace UUID with /dev/sdb1.
I can also access (read/write) ext02 when mounting manually.

But mount -a failes:

# /etc/fstab...# ext01UUID=4f384179-5f1d-41b6-9cb0-a9cc1cbc15b4 /media/ext01 ext4 defaults,uid=997,gid=997,umask=0002 0 0# ext02UUID=11f26526-81e1-4095-9d19-f68a81429c5d /media/ext02 ext4 defaults,uid=997,gid=997,umask=0002 0 0

Results in:

$ mount -a    mount: /media/ext02: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.

dmesg output:

The uid 997 exists, it also works with ext01.

Any ideas how to get this work?
