You need to configure the asset list per the contract specifications:

https://www.cmegroup.com/markets/equities/sp/e-mini-sandp500.contractSpecs.html

Assuming this is a USD account, PIP should be 0.25, PIPCost should be 12.50, leverage should be zero, and MarginCost should be the maximum of initial and maintenance margin (per your broker). (Or configure MarginCost or Leverage conservatively.)
