Buy a cuttlefish bone from the pet store (they are given to pet birds so lol in the bird section) and put that in the water. It will float and help get those parameters to the right levels
I suggest spending a bit on a liquid test kit. Much more accurate compared to test strips. Amano shrimp are pretty hardy they should be fine.
Gh is mineral content dissolved in water like calcium magnesium
Raise gh by remineralize with something like equilibrium
Lower gh by water change with rodi water
Kh is carbonates and bicarbonates in water
Raise kh with baking soda
Lower same way with rodi water
Crushed coral also could be used to increase both kh and gh

The kh is really high and it shouldn’t be higher than gh, seems like you have a type of rock that’s leaching carbonates into the water
