Your mistake is the extra unnecessary pipe, the last one.

| means "everything between this pipe and the percentage sign, but
only if this thing exists."  It can work in either direction.  So, to
do what you want (where the colon and space only appears if the
subtitle exists):

%TITLE%%: |SUBTITLE%

Or how about this, as an example in the opposite direction:

%DIRECTOR| was the director.%

So, in summary

%Some Stuff|

or

|Some other Stuff%

But never

%|

or

|%

Make sense?
