electronic signature AX 2012 set up

I am trying to set up an electronic signature in AX 2012 for a table/field which is in addition to the existing standard options

In Org admin>Setup>Electronic signature>Electronic signature requirements I created a new record and the selected "Properties"

When selecting a table to reference for the signatory control it only refers to DAT entity. I am in another entity but I can't see where/how to change this. I suspect my e-signing isn't working as I am pointing to the wrong entity

Does anyone have any advice please?

thanks
