Bug in the gradient pallete of illustrator

[Yosuke_24]

 

In the gradient palette, you can only change the slider and color as shown in the picture.
Buttons for changing opacity, angle, and partial color deletion using drop-down boxes are missing, making editing with this pallete is impossible. Though I can only use the gradient tool to edit, crazy hard to do so.

Does anyone know of a solution?

I tried restarting the PC, uninstalling and installing the application, etc.

Adobe Illustrator version: 26.4.1

In the Palette flyout menu turn on "Show Options".
