I don't think that the typo has any bearing on the validity of your permit. You qualified and were issued the permit and everything else is correct.
It appears that the only thing that remotely relates is:
NRS 202.3667 - Permittee to carry permit and proper identification when in possession of concealed firearm; penalty.
1. Each permittee shall carry the permit, or a duplicate issued pursuant to the provisions of NRS 202.367, together with proper identification whenever the permittee is in actual possession of a concealed firearm. Both the permit and proper identification must be presented if requested by a peace officer.
2. A permittee who violates the provisions of this section is subject to a civil penalty of $25 for each violation.

The "proper identification" that you carry has your correctly spelled address.
I'd get the permit corrected as soon as possible but it shouldn't affect your carrying concealed unless, by chance, you have to turn in the old permit before you can get the corrected permit.
