Library variable in the bottom panel not visible after enabling

Hi all,

I have enabled the Library variable preview function. 

I can create the resource and create variables. 

However, when I create a new Data Pipeline I don't see the Library variable (preview) in the bottom panel. 

Do I miss a step in the process or is it just that this is too new??

Thanks.
