Missing Animation Curves in Graph Editor

[DigiFX]

EDIT: This is resolved. See the reply for the solution.

Hi,

Can someone help me out, I cannot seem to get animation curves to display on referenced files in my scene. I don't recall seeing this issue in the past. 

Running Maya 2019.3.1

Resolved.

I just realized that when you hide groups in the outliner, it affects key visibility in the graph editor. I did not know this until I accidentally came across an unhide from the outliner option in the graph editor. 

I thought hiding in outliner only affected object visibility in outliner... guess not!
