Admin Permissions keepinventory?

Hi!,
I have created a server and everything seems to be working alright EXCEPT...
when I login I am a regular player, so I added myself to admin under the server file.
I am able to do all of the default admin commands and abilities just fine this way, except I am unable to keep inventory on death.
I have this ability set up in general and it works for regular members, however I am unable to have the same abilities in admin.
I tried adding a general section in the admin permissions file, but still nothing. I can not for the life of me figure out how to give myself keep inventory as admin. The only way I can seem to get around this is to do my admin functions then shut down the server and remove myself as admin from the server file and restart the server again. This is frustrating to other players. What am I doing wrong. I have been searching the forums and can't seem to find this subject.
Thank you!
