blocking in advanced ip config of sm's

hello all i have a very strange one

when i am programming the new sm’s for deployment and i go into advanced ip config to block some of the one’s i dont want people using when i check mark the few that i want to block and go apply all get checked.

as soon as i uncheck and save again same thing.

i use my laptop for all of the config and i have programmed more than 100 sm’s with out this happening,

any comments.,

Update the software and see if that helps. Otherwise resetting to factory defaults.
