As for mystery #1, I guess you'll have to talk to the company's
customer service folks about an exchange.
#2 isn't much of a mystery. Nearly all of these airplanes are old
enough that they've had the ELTs replaced. The orientation for the
finger hole was designed for the original ELT and the numerous types
of ELT's that have been used as replacements never considered
installation in this one model of airplane, so they are where they
are. There was a Piper like this that crashed in the Appalachians a
number of years ago and the ELT was loose. It injured or killed the
pilto as I remember.
Just make sure the orientation is correct and that the antenna
conneciton is good and not corroded.
