Raid Protection Not Working

I have offline raid protection set at 50%, but the base damages just the same as if it didn't have protection at all. The weird thing is that the shield on the top right shows 50% protection when I hit the base, but when I do /pro it shows 0 protection. I have the config setup correctly I believe. 

    "Protection levels": [
      {
        "Rank": 1,
        "Online protection percentage (0-100)": 0.0,
        "Offline protection percentage (0-100)": 50.0,
        "Hourly cost per authorized player": 0.0,
        "Hourly cost per floor": 0.0,
        "Hourly base cost": 0.0,
        "Cost per damage protected": 0.0,
        "Max protection time (hours)": 24,
        "Delay for offline protection (seconds)": 900,
        "Delay after taking damage (seconds)": 1800,
        "Damage resets timer when owner is offline": true,
        "Allow tugboat protection": true,
        "Allow barge protection (requires Barges plugin)": true,
        "Founder Limit": null
      }
    ],

seeing this in console

We found that the solution to the original problem was to set "Damage resets timer when owner is offline" to "false"
