That's super they did that (y) You should be fine,
Remember though it's a completely NEW application for something (this time it's the yearly extension)
so it will require all new copies, passport data page, entry stamp, Non-O visa, 90 day stamp, TM30, lease, etc
and
a filled out TM7 application for extension form along with a passport sized photo and 1900baht .
