Double kuzu - in back of mezuza
1) since these shemos are not me'akev at all the mezuza, it is kosher with 2 kuzu.
2) it was permitted to erase the first kuzu [more accurate from the (lacking) samech down], since these are not true 'shemos' that are forbidden to erase, rather 'kinuyim' (other secondary/derivative names) that are not kodesh and permitted to be erased for great need as tikun. That should of been done rather than write a second one.
