Some charts have the same note count for every difficulty level

[someot]

Some charts are labelled as having multiple difficulty options, when in reality the same chart is applied to all difficulty levels.

This means the advanced search option for difficulty levels can't always be considered accurate, so you need to check the note count for every song to check if it's one of these miscategorized charts.

Example: captaintoasty's Comfortably Numb chart.
