I created new ticket with this issue on github, they reply me that it will be fixed in next releases. Thanks for help.

I can't resolve my main issue I had to disable "Show history rates" in setting because when it's enabled then only source I can choose is "BictoinAverage" and then this problem occur. When I disable "Show history rates" then columns Currency Amount and Currency Ballance disappears bu I have at the bottom my current balance showing correctly. So is any bug with this and I would send this to developers but don't know how?

please tell me more, how should I update electrum to new versions, uninstall older first or simply install it over? with second option electrum create new other .exe file to run program.

Hi,
my electrum after upgrade from 2.6 to 2.8.2 shows on bottom "No FX rate available" and in History on columns Currency Amount and Currency Balance it shows "No data" on every transaction.Help.
