I know this was an issue in previous versions of LR, but I've been told it's been fixed in the latest and it's not. If this post is a duplicate to a previous post, please mod accordingly.
When applying a preset to an image, the color adjusts slightly from what is shown in the preview when hovering over the preset in the list. Even once applied, when moving the cursor over the preset the color shifts back to it's preview state. Once the cursor moves off the list, the color reverts back to it's alterd applied state.
