Shimano Deore M5120, idk what is going on. It shifts up on the cassette when I shift down on the shifter. It shifts down on the cassette when I shift up on the shifter LOL

What shifter is that?
For the rear cassette, gears are numbered from large to small. So you’re shifting from 8 to 10, not 1-3.
Set that shifter to its highest gear and readjust the tension on the derailleur cable. Should be able to cycle through all the gears then.
