OS X doesn't automatically "fusion" your drives together. Fusion Drive is ONLY supported on specific Mac models as shipped by Apple.
So unless you followed an article on how to set up Fusion Drive yourself (which is UNSUPPORTED), I'm not really sure what you're referring to. And if you did, perhaps you're seeing why it's not supported; Apple doesn't (and can't) test all configurations people have in their systems and there's the possiblity for problems.
"After looking online how to un-fusion the drives I got my system back to normal."
This would cause the issue you are describing. You corrupted your file system by destroying the logical volume.
When I restarted the mac to do an fresh install I get an issue stating that there is a drive error in both my SSD and HDD in disk utility on the boot up screen. it then says, do I want to fix it, I ok it but nothing happens. If I come out of the boot mode and restrat the OSx normally and the go into disk utility and check my drives everything is ok, so what gives."
If your volume was encrypted, the recovery partition won't be able to repair anything until it is decrypted. If you can't repair it:
According to Apple's FAQ, repairing a fusion drive erases it. Essentially, DU must reformat the drives. This makes sense:
