another atrocity from steemit.com

Typed at 2018-7-13

I placed a selling order:
https://steemd.com/tx/db45421eda38d0511f153b83acf2da30dc6532c4
Then, after it was partially executed
https://steemd.com/tx/e046c1b9f20ae23b5514dd10e8c2e98b9762113e
I wanted to cancel it, and place a new one, but my order did not appear below, so I could not cancel it.
A refresh and an attempt to access the same page again without a refresh from the browser both failed, until one of them worked, and it was only due to luck and tenacity that I eventually managed to cancel my order:
https://steemd.com/tx/7897810eefa5acf8f58a8367955e40a7994a7c5a

Now after I cancelled it, it seems to appear and to be uncancellable, and even worse, it appears that I have less Steem than what I have:

It shows that I have 0.399 Steem whereas I have 1.845 Steem.
I could not place it in the same screen in an appropriate way in order to show it, I hope that you manage to see it in the upper and lower edges.

It was not the first time that it happened to me.
