From your post, I have no clue what the trouble is. I will just add a comment though ...
It looks like you have a LUT you've loaded into the system ... where did you put that on the computer? I hope not in the Program/Package file folder with the included ones ... just for general info, ALL user-supplied LUTs/Look files should be put into folders located in the following chart:
You need to create the 'final' folder in each location, the Technical folder which will be accessed by the Basic tab drop-down, and the Creative folder which will be accessed by and shown in the list in the Creative tab.
The program will take all your provided LUTs/Looks, and the ones in its own files, and list them in computer alpha-numeric order. So to make mine appear first, I add a prefix system ... a number, space, letter.
01 A low-sat shadow neut
01 B low-sat highlight neut
You should get the idea, I group them by function/use as I would need them.
Back to your query, could you please add more information and detail?
