Did you add replay protection
No idea what that is or if I did

I'll google it, but right now I'm just sending a very small amount of BCH to the exchange to make sure everything works.
or did you accidentally send your BSV and BCH-A to the same exchange too?
As far as I can tell there's only BCH in the Electrum Cash wallet. I downloaded it from here:
https://electroncash.org/ Got the portable version.
Would screenshots help? Of what?
