Assets disappearing from composition when moving layers

[Trevor23820490ovxk]

I'm a complete beginer with AE, but while working with a template I got today I was moving some layers around to fit with music I'm putting it to, and for some reason one of the "Boxes" I have lost all of it's insides. I can't figure out why or how to get them back.

It looks like the boxes are nested comps (pre-comps). Open up the problem comp and see if the missing layers exist. If they are, then try collapsing transformations or turning CT off. Make sure the contents are not set to be Guide layers.

turns out I'm just dumb and didn't increase my asset durration to match my new project durration. So my pre comp's were just sort of "timing out" by the end of the project haha. Thank you for the answer though!
