Problems with resizing a partition

[Aravisian]

In order to resize, you must have space to resize into.
You can imagine what would happen if you resized a partition, thereby overwriting data on a different partition.

This is true of moving a partition, as well. You cannot drag and drop a partition as it is actually physically written on the disk. You can expand its free space or shrink its free space. You cannot move the data.
That, would be a different process entirely.

You cannot move or resize a partition that is mounted. So be sure that you are booted into the LiveUSB running Gparted.

Your ext4 filesystem (Zorin OS) is located within the extended partition.

It's alright, do you think i should reinstall both OSes after wiping the entire disk? Theres not really much personal data, it's mostly the updating and installing stuff that takes a while (my ethernet cable takes about half an hour to work).

If that means fixing the problem i might try to do it.

Given the above, this might actually be the easier and safer route. You would have to reinstall, but it would give you the ability to align all partitions in the size and order you want, right off the bat. It would solve resizing and data.
Since this is not a complex installation of Zorin OS with lots of personal data and tricky installs you had to set up - It is the way I would go about it. Fresh install lined up out of the gate. Much easier than resizing and dealing with residual 1mb partition gaps left over.

Yes, i agree with everything you said. And in the end i decided to reinstall in order to get all partitions to my preferred size for each system.

Just found weird that once i deleted the extended partition, the "free space" that were divided then became one. And later when i installed Ubuntu Budgie, the 1MB partition came back, not sure if that is normal.

It was WAY easier than messing with GParted, though i had to login in all my accounts and reinstall everything again.

I will set your post as the solution, and thank you for helping me!
