Código CSS duplicado

Olá,

Acredito que o código css (style.css) disponibilizado no curso está com diversas instruções duplicadas. Desde o primeiro seletor body até .form-button:hover.

body {
  margin: 0;
}

.app {
  display: flex;
  align-items: center;
  justify-content: center;
  width: 100vw;
  min-height: 100vh;
}

.todo-list {
  background-color: #0B2027;
  font-family: "Space Mono", monospace;
  padding: 1rem;
  min-width: 400px;
  min-height: 300px;
}

.title {
  border-bottom: 1px solid rgba(246, 241, 209, 0.5);
  font-size: 1.5rem;
  font-family: "BioRhyme", serif;
  color: #F6F1D1;
}

.form {
  display: flex;
  justify-content: center;
}

.form-input,
.form-button {
  border-radius: 0;
  padding: 0.75rem;
  font-size: 0.75rem;
}

.form-input {
  outline: none;
  background-color: #F6F1D1;
  border-color: rgba(255, 255, 255, 0.1);
}

.form-button {
  border: 1px;
  background: #F6F1D1;
  text-transform: uppercase;
  cursor: pointer;
  margin-left: 0.25rem;
