Help with masking

[pallofisu26333949vlgd]

I am trying to highlight a point using a mask. In this case I am masking lumetri color effect so that a spot would not be affected. Problem is with the mask. I can't get it to the position I want, as you can see it's not at the position I am trying to put it at and its incorrectly sized. I am using a transform effect on this clip, so could it be that? I tried to do this effect with 2 of the same clip where the other one has a opacity mask at the position where I want to have no lumetri color effect or whatever else I would want. Using 2 layers I had the problem where I would have the mask at the position where I'd like it to be, but actually be where the mask is applied to a spot hundreds or thousands of pixels away. I am really struggling with masks and would need some help. Also it'd be nice if you could drag shapes like square and eclipse into a shape, size and position you want, and not have to insert one with the default size in the center

The blue is the mask, and grey is the lumetri color effect I am talking about. If you didn't understand from the pixelated picture

I would guess this is definitely being caused by your Transform effect. Try dragging the Transform effect above the Lumetri effect in the Effect Controls panel. This should help resolve the issue.

You could try nesting the clip after you have done the transform and then add the mask effect to the nest.
