Are you using other modlets? If so it's likely caused by 2 modlets accessing the same setting. Its checking for a default value of the setting, that may have been changed. You can open the following file:
P:\Program Files (x86)\Steam\steamapps\common\7 Days To Die\Mods\Xajar_KillRewards\Config\entityclasses.xml
Remove this part of the text near the end of line 4,
@value='0.02'
This should make it set the value, regardless of the current value. If you want the other modlet to override mine, just remove or comment out that entire line.
