X Mark on Object in Illustrator

[Al Saqr_mouse_point]

Dear Adobe Community,

I’m encountering an issue in Adobe Illustrator where one of my objects has an X mark on it. I’m aware that X marks typically appear on linked objects or images, but in my case, the object is neither. Could anyone help me understand why this might be happening and how I can resolve it?

Thank you in advance!

It says non native art in the comtrol panel. Where does it come from?

One of my clients sent their logo file as a PDF. I opened the file in Illustrator.

About non-native art from the manual:

When you import artwork from an Adobe PDF file, it’s possible to introduce data that you can’t create within Illustrator. This is called non-native art and includes monotone, duotone, and tritone images. You can also generate non-native art within Illustrator by using the Flatten Transparency command to preserve spot colors.

Illustrator’s ability to preserve non-native art is useful in many situations. For example, Illustrator maintains the spot color information in linked PDF files when you output color separations.

By default, non-native art is labeled <Non-Native Art> in the Layers and Appearance panels. You can select, move, save, and perform basic transformations (such as scaling, rotating, or skewing) on non-native art. However, you cannot select and edit its individual components. In addition, you must rasterize non-native art before editing it with the liquify tools.

To convert non-native art to an Illustrator object, choose Object > Rasterize.
