The revision graph shows you the copy-history of the item you show the
graph for.
Which means, in your case here it shows the graph of "Source" from HEAD.
And that source was added after another completely unrelated folder
named "Source" was removed. Since the first "Source" folder has no
connection to the second "Source" folder, the revgraph doesn't show
anything for the first "Source" folder.

Problems: no.
But you've lost the history. For SVN, those two folders have no relation
or connection at all.

If you want to do a proper "replace" in the future, leave out step 3 in
your example above: after 'svn rm', add the folder and do 'svn add' and
*then* commit that.
And if you want to keep the history: don't delete the folder but copy
the files over the old ones and then commit.

Yikes!
Please update.
