VGUI Menu Not Properly Refreshing

[RDK]

This is a basic item container entity I've been writing, the items are transferring and everything is working fine except for when I attempt to repopulate the player inventory panel. For some context the inventory object of the player is a table that get entries from a MySQL database inserted into it on player load, giveitem and removeitem update this table and sync it to a MySQL database, the refresh function is RefreshContainerMenu(). There are no errors serverside or clientside. I'd really appreciate some help on this.
