Button inconsistencies inside Donut platform

Problem to be solved

Buttons inside the Donut platform are not consistent.
Following are the required changes:

• Convert all the buttons from the "Round" shape to "rectangle" shape except tags.
• Color of the buttons should be consistent
• Font of the color should be consistent
• Remove shadows from the buttons wherever it is there.

Once these issues are resolved then please upload the screenshot.
