Composite C1 console edit button available for non translated data

Composite C1 console edit button available for non translated data

We are using Composite C1 version 2.1.1 with static C# data. This data is
localizable (ILocalizedControlled) and is shown on top of the data tree
(TreeDefinitions\GlobalData.xml). Users are able to translate the data to
their selected language, but somehow it is possible to "Edit" the data
before translating it. This means that when they do it wrong (i.e. in
stead of first choosing "Translate Data" and then "Edit", choose "Edit"
directly) translated data will appear on the source language site. Which
is very annoying because the source data is lost as well. Seems that when
choosing a data item only "Translate Data" should be possible, but now
four buttons are shown (Translate Data, Edit, Add and Delete). So I would
like to be able to change this behavior, but can't seem to find where or
how to influence this.
Hope anyone can help.
