Properties in reports

[Bec]

When you run a report in Visio there are a whole lot of properties that are
not needed that you have to untick to make sure the report runs properly
(when customising the report). I have renamed a lot of the custom properties
to make sure all the devices match up in the report and this has generated
properties that must now be deleted. I have saved my Visio file as a webpage
and in the advanced search area all these properties still show up. I cannot
find out how to delete them. They are not sitting under the custom properties
so you can't go into define and delete them in there. I can't find out where
they are located to delete them. Any thoughts??

Let me know if I haven't made this clear enough.

Thanks in advance
Bec
