Well that does suck. Don't own a 97 yet, but here's the typical stupid questions[emoji6].
Did you thoroughly clean and relube before shooting?
What ammo were you using, and did you try different ammo?
As to the auto forward when inserting a mag, many in here consider that a plus. Very typical for CZ's, some guys can get it all the time, some, (like me) can't hardly get it to do that.
You can give up on it if you choose, you may have gotten a lemon. (Happens with every single manufacturer)
I'm sure someone will be around shortly with more help. You can always send back to the mother ship if you still have issues. Pre paid, and great CS.
Oh, ha ha, I see I must be typing to slow[emoji850]
