ModalPopupExtender Not Popping Up - Loads in table

I have a page when I click a certain set of sequences (Delete then OK to Delete then Add New) the modalPopupExtender displays inside of a table.  It supposed to be in a lightbox type display.  All other times it pops up correctly.

Here's the front page .aspx
