Custom luts no longer have any effect

When I make a lut using either Luttools or lightrooms lut feature the lut seems to have no effect, whereas I made one before without any problems.
The lut is the correct size at 32 x 32 and the lut itself is the exact same dimensions at 1024x32.

My previous working lut works in the game in question but replacing that with my newer lut leads to it having no effect again. Any ideas what could be wrong here?

Heres my lut if its any use, if anyone would help me to troubleshoot this.

Solved

Turns out I was putting the lut capturing tools at the bottom of the load order rather than the top, so they weren't having any effect on the lut.
