Help! IES profiles not showing? 4.24

For some reason no IES profiles are showing when you attach it to any type of light (point,spot)

The light profile does not actually change. If i select the light, it will show me the IES ‘shape’ and direction, but the light itself stays exactly the same. If i chose to use the IES intensity, it just blows up the light super bright.

Can anyone help? this is so frustrating! Is there something I am missing? Some sort of override?

Could not understand what you did wrong. I just checked with 4.24.3.

If you could post a sample bluprint file we could check it for you and help.
