When calling estimatesmartfee https://developer.bitcoin.org/reference/rpc/estimatesmartfee.html from the command line like this: bitcoin-cli estimatesmartfee 6, I expect some reasonable results as well as different results depending on the provided conf_target parameter. Lower conf targets should return higher fees.

{
  "feerate": 0.00001000,
  "blocks": 6
}

All the time. No matter what conf_target parameter is passed, it always returns 0.00001000, which is also much too low.
