Hmm? Not quite sure what I am looking at.

There might be an object on top of another object (a pink object) and with transparency applied to the top object.

Select the object, and if the status bar (lower left of screen) says Group, hold down the Ctrl key and click on the top object to select part of the group.

Then switch to the Transparency Tool (the wine glass icon on the main toolbar) and see if the Infobar at the top of the screen indicates transparency.

If so, set the transparency shape to None.
