When I'm logged in as admin, I'm able to move customers between resellers. There's an pulldown "from reseller" and another one "to reseller". However, the first one shows, beside of valid entries, "N/A" as selectable value. By doing so, I'm running into an exception.
I don't know if the migration led to this problem or if there's a bug. It's not a big thing - just want to report it.
