To make them work you need to click the ... on the top right of it and if there are two things ex. PC, Mobile. You can chose to make it a sub category which will make the leader boards separate.

I think there should be variables for (No powerups / powerups) and (No deathcoin / deathcoin)

On the 95% category do I have to reset my data? Or just beat every challenge and beat 40/20?

Is there anyy chance of a SCP CB Ultimate Edition speedrun?

Just use livesplit smh
