Datagrid column with muiltiple buttons and visibilty rules

hi guys,

i have a datagrid wired up to a server controller API
image

there is a field here which returns a bool --> Member

on page load, i invoke the method to call the API and then set the ${result} to a parameter

i use that parameter as the data bind for the datagrid.

in the datagrid i have two buttons in one column;
the buttons have the same visibility rule

when build and access this page, i'm getting a mixed result, i expect there to be a single button on each row as a red would show when Member = FALSE and a green would show when Member = TRUE

however i'm seeing both buttons in one column and nothing in another .... this doesn't match the API response or how i think this shuold work.

can anyone spot the issue?

one of the buttons needs an inverse visibility rule..... OMG.... rookie mistake
