Newbie seeking help with unexpected charges

Hi,

Linode newbie here.
(got account few years back, but using it properly for a first time now)

Please, help me understand Linode billing and costs better.
I just can't track the reason for some unexpected charges.
Probably I have done something to incur those charges, but I am having trouble locating that reason.

I have started my first node from the web interface (nanonode - one click LAMP) approx. 24 hours ago.
At that time I also activated one domain with the defaults (master), but without adding any specific to the then active node records (like A records, etc.)
I deleted that node after ~15 hours.

(In the mean time I've played a lot with the Linode web interface options, but reading my activity log in the https://cloud.linode.com/events , I can't tell for sure what is the cause for the unexpected amount charged. I also copied the node image to my desktop with rescue mode, ssh and dd my first nanonode, before deleting it.)

At that time the "Uninvoiced Balance" was $0.22 - around twice of what I've expected, based on nanonode $0.0075/hr. and not much outbound bandwidth used (less than 1GB) or something else chargeable, that I am aware off.

I left my domain active and unchanged, even after deleting the nanonode and I'm wondering if that has something to do with the charges? I have not deleted it.

I don't believe that it is the reason, but I also have activated object storage (free until the end of next month) around the time I started my first node. I have not canceled it too.

At the time of writing this (it is 7-8 hours after I have deleted my node and stopped/deactivated/removed anything I can think of, except what I have mentioned above) I am still incuring charges. "Uninvoiced Balance" is now $0.28.

And while at that scale, the amount may seem negligible, not understanding the charges is a problem for me and I would appreciate your help in that regard.

As a side note, more detailed log of what exactly is contributing to the overall service charges would be nice. If there is such thing, I just couldn't find it on my own.

With exception of the above issues, Linode web interface feels pretty comfortable and intuitive.

I am pasting my event log after the post. Changing actual username with "MyUsername"
