You've started asking Clariti to show more information and data in the columns, but now it's showing the remaining options greyed out.
This is because you've selected the maximum number of fields that are available to show at once! This can change depending on your options, as each field needs a different amount of space.
To change your selections, all you need to do is deselect some of the options and choose new ones!
Here you can see that I've deselected some options, but others are still not available. This is because they need more room! Continue deselecting to see more options.
