It might take a little while for the changes to catch up. You can either wait for the mod to go to sleep (about 30 minutes of non-use), click on soft reboot (Tools . Diagnostics > Reboot Device > Soft Reboot at the top of Escribe while the mod is connected), or take out the batteries for a few seconds and reinsert them.
Let me know if this takes care of your problem. I will also look up a link for the LG HG2 discharge curve if you want to Upload it to your mod.
Edit: Here's the link:

PS In the same place (see the picture in my above post) I have my charging mode set to Maximum Puffs.
