BP Template Pack Adding Pages with Multiple Copies

I believe I have created my own mess here, but would love it if someone knows an easy way to clean it up.

I have installed and uninstalled BP Template Pack several times as I have tried out different themes for my site. Now that I have decided upon and built a child theme, when I go to assign pages to the BP components, they get assigned permalinks such as: ....members3/groups OR forums3/forums/forum

Today I tried to put in a vanilla install of WP and start from there but ran into some big troubles with my child theme. After restoring the site, I think I know all of the issues that went along with the issues regarding the child theme. So...before I try this all again tomorrow, does anyone know of an easier way to clean up the data? (I assume this is caused by multiple entries in my database?)

Thanks in advance!
