It is moving around because it is unhappy and trying to find suitable conditions to survive, which do not currently exist in your tank, as is! As others have said anemones almost never do well in a tank so young. Best option is to return it or have someone with a stable and established tank care for it.
You ca is very high as are your nitrites! Salinity is high as well. Reducing Salinity will lower your CA some as well as other levels. Nitrates are high, but fine for soft corals and BTAs, as they are a food source for BTAs. The fact you have nitrites and such high nitrates is indicative your tank is not stable and far from established. Zero phosphate is not good as almost all living things need a little phosphate!
