Bugfix: remove extra %T in default placeholder.

The issue relates to the default path used for placeholder (which attempts to be the same as the pre-placeholder default). The intention was to have the path be something like $BASE_DIR/Light/Blue/... but instead the previous/buggy code generates $BASE_DIR/Light/Blue/Light/... (duplicating the capture type) as $T is the Type (e.g. Light, Dark, ...).
