Colored tags are retained on some older files but are converted to grey band with colored dot on others. Tagging a new file always results in a grey colored band with selected color as a dot; adding a second tag results in two colored dots on grey band. However adding a second tag to a normally colored file (i.e., no grey band) works. Removing grey tag from TotalFinder preferences does not make any difference. Uninstalling and re-installing 1.15.1 does not make any difference.
