Some layers in a pre-composition not showing in main composition

I have a main composition named RENDER

inside it has pre composed layer named Christmas Light, and in this precomp, i have some pre-composed layers cosist of text written "Christmas Tree Lighting":

Those layers & text of "Christmas Tree Lighting" are visible in Christmas Light comp. However in the main comp RENDER, it is not.

I have tried to export the Christmas Light  comp only. But the output result not the text Christmas Tree Lighting as well.

Please advise for the suggestion guys
