That's how it should work, not sure why you think this is a bug.

When TMerge is started and you have the "jump to first diff on start"
option enabled, TMerge does exactly that: it jumps to the first difference.
Since your file only has one difference, the "prev/next diff" buttons
are disabled - they wouldn't do anything.
When you hit reload, TMerge doesn't jump to the first diff anymore but
tries to keep the current view as it is. But a reload also means doing
the diff again, so the currently selected diff is discarded. The cursor
gets set to the top of the view. And now, there *is* a "next difference"
(the first and only one in this file). So the button gets enabled again.
