When adding a figure caption to a plantUML generated image in word the reference bookmark to this caption gets messed up when UML.* or UML.1 is run: the reference to the caption will be changed to include the referenced image itself then. The plugin apparently updates the figure caption bookmark to include the image itself. This should be not be the case and should be fixed. When I explicitly add an extra hard enter between the caption and the image this strange effect does not happen.
