Slide masters in PP 2007

[Misha]

I have created a new 'Text Only' slide master in a presentation. However, for
some reason I now have 22 instances of the 'Title & Content' Master, and
cannot delete them. Each time I use the custom master, it seems to generate a
copy of the Title master.

I do not seem to be able to delete any masters.
Any suggestions?
Thanks

You can't delete a master or layout if a slide is based on it.

Did you insert slides and choose "keep source formatting"? That's one way to
end up with duplicate layouts and/or masters.

(The big ones are masters, the little ones are layouts. See
