Above image shows an adjustment layer identical to the one below, except for the eye icon. I don't know how this happened and how to fix it, but I do know it messes up my color correction.

What the weird icon produces > Gyazo - a8e6159a086e8901ac1ca80e54f04c65.png
Please help ;(
You've turned one layer into a track matte for another or you've changed the blending mode to something other than "Normal".
BTW it's much easier to diagnose your problems if you include a screenshot with all of the properties of the layer you are having problems with revealed. Simply select the layer in the timeline and press the u key twice and then take a screenshot of your whole project. Then just drag the screenshot into the reply field on this forum. External links to screenshots are a pain to look at and small details like the ones you showed don't tell us much.
The first eye icon is meaning that your layer has a blend mode
and the second normal eye is meaning that it is Normal
