multiple database entrys rather than modifed ones on tblpricing

[security_man]

not sure if i am missing something or not, but i am seeing multiple pricing entries for the same addon after i make a change to it. what i am seeing is below (not the entire table, just the duplicates), my question is am i seeing something that is supposed to happen or have i found a bug? and either way is it going to hurt anything to remove the duplicates?
