This is due to one of the few functions that was brought from the old
exporter: `org-export-solidify-link-text'.

That's because targets (that is <<...>> or #+NAME: ...) have no
limitation on the characters allowed in their value, which can lead to
problems when translated into foreign code (i.e. an % sign in the target
when using the latex back-end).

So, the function replaces forbidden characters with hyphens.

Besides using filters, a solution might be either:

1. to remove colons from the forbidden characters.
2. to limit the characters allowed in targets and remove
   `org-export-solidify-link-text' altogether.
