NullReferenceException: Object reference not set to an instance of an object

Hi! I have an issue, could you please check my .json settings and help me solve it? Thank you.
p.s. What im trying to do is to add more seeds, and some minor adjustments here and there.

Here is the error:
[Oxidation.Wiper] [WARN] Found a pending 'forced' wipe request, executing..

Never mind, this below worked.
I added back the "FIles" and "Blacklist" lines back in as it was. I dont know how to disable them, but no big issue since they are just placeholders.
