Hi i am using Photoshop CC 2019 on window10 and Wacom bamboo CTH 460 tablet which is pretty old.

The setting you show for you brush has control turned off. These show mine control is set to pen pressure but Photoshop does not see that I have a pen the warning triangle.

After I use my Pen Photoshop see that I have a pen and changes the palette to match and changes the brush preview as well.

Set it to what you want to use however, some brush types do not support shape dynamic like mixer brushes with bissel brush tips. You seem the be using a brush type that does not support shape dynamics what you posted looks grayed out in that area
