Can't succeed to apply colors on a gradient - (Illustrator 26.3 Windows)

[Simon30887964flb8]

Hi everyone !
Glad to post my first issue on the platform.

I ask for your help, cause I fail to find the solution.

In fact, i created an object (i working on this tutorial where i'm stop at 4 minutes) on which I selected a color, and when I want to "Create a gradient mesh" [Object] the gradient is only black and white. However, my menu shows me that the gradient is a colorful gradient (as you can see on the picture).

I absolutely don't know hot to fix it, so there are a lot of frustration, because i just begening to use this amazing software.

Thanks a lot for your response, and have a wonderfull day 

Simon

Can you please show a screenshot that contains the document title bar and the Layers panel with the object in it and the appearance panel?

[Simon30887964flb8]

As if ?

[Monika Gause]

There is a special appearance applied to that object. Could you please make the appearance panel longer?

Thank you. What do these "Other options" say?

[Simon30887964flb8]

Thank you for your time ! In "other option" from [opacity] I have the possibility to create a mask

Can you please upload that AI file to Dropbox or the like and post a link in the forum, so we can take a look at it?

Gradient mesh is not compatible with the gradient tool! (The Gradient panel is not open in the tutorial)
If you have a gradient on original oblect you get black in centre. Don't worry about it, you can select any mesh point and adjust colour and/or opacity at that point.
