hmmm... you bought a cassette that won't work with your previous derailleur, then bought a wild eyed, off road, clutched, MTB der., struggled to route the cable correctly, but still can't sort things out..
At this point, i'd suggest finding a good bike mechanic to do the work next go-round, ok?
and never cut the der. cable until you KNOW the setup works.... although, in this case, the now smashed cable section will be inside the housing, if a more conventional derailleur gets installed.
and i recall something about MTB and Road Rear der. and or cassette spacing/pull ratios possibly diverging at the 10sp. level.... which would neatly explain the "adrift" gears....

Everything you said there is correct. My local bike shop said I had to invest in 600 pounds worth of 11 speed setup. A guy who recommended the derailleur had it on his bike. He fixes all the e bikes in my city. So I thought he was pretty sound for advice. I did think about if Road Bikes and Mountain bikes 10 speed cassettes had a different spacing which maybe causing the issue. Thanks
