Ubuntu – Can’t automatically mount ext4 partitions under Ubuntu 14.04 (but can mount NTFS ones)

So I just got alongside my Windows 8.1 a cool Ubuntu 14.04 and quite happy with it (my default OS now). I just have a problem: the fact that I can't mount ext4 partitions at boot is quite annoying. I have the following setup: 1x Intel SSD with 3 partitions: the root ext4 (ubuntu install point), a NTFS one (where the win 8.1 lives) and the swap. Everything on this disk mounts at startup by default, without problems (the root mounts, obviously, swap works, and the NTFS automatically mounts and shows up in Nautilus). I also have other 2 HDD disks. Both have one ext4 partition and one NTFS. I tried making them mount at startup using the Disks app. I made identical settings to all of them, the NTFS ones mount, the ext4 give an error. I'll explain with screenshots:

This is how the default automount for my root ext4 looks (and perfectly works).

This is how I set up the NTFS partitions, that perfectly auto mount:

And this is how I am trying to set up my ext4 partitions to mount at startup:
By default, the mount setup for non-boot ext4's looks like this:

I try setting it up like this:

OK for now,…it asks for password:

Now it looks like everything worked:

But the partition will not mount. If I restart my PC or I try to use the ext4 partition set to automount, I get:

And I am unable to use my partitions until i go to disks and set them to automatic mount options again. Also, if i set up and restart without remounting, before I get to my desktop, I get that error on the last screenshot with the "Bad superblock".

I know this question has been asked, but no one had the exact problem as me, and some say it is impossible to fix? I don't believe that. On my server I setup automount with fstab. I can do this here, but i need to keep the EXACT labels and mountpoints because I have some path dependent applications like Deluge.
Thanks.
