What is the difference between these two icons for nested sequences?
Hi there, I make nested sequences a lot for multicam edits. However, sometimes my nested sequences will not open as the others regularly do, and I can't figure out how to do so when I need to color correct the nested video tracks. This always happens when there's a different looking icon then the normal looking sequence icon. Here are the two icons with the top one being the one that won't open with a sequence as the others normally do:

Can' someone please explain the difference? And if it's possible for me to make the top one like the bottom one? Thank you.
