Colorgrade clips won’t work

Okay in the color section when timeline is selected it will no longer color any clips, any idea how to fix this? How do I reset things because this is the only way I know how to color all the clips at one time

In the node graph you have selected timeline.

You need to change that to clip for individual clip grading, or in timeline add a node for the complete timeline grade.
