Unable to see Filter Fields for the Capacity Planning portal.
Here the Buttons are set to a white color and therefore unable to be seen.
We can fix this by setting the button color to something more noticeable, such as black.
1. Navigate to Service Portal > CSS
2. Check for anything that sets the Button text color to white
4. In the button CSS, update anything that has "color: #fff;" with "color: #000;"
5. Save the record
6. You will need to clear your browser cache to see the change. You can also verify on a new Incognito window in Chrome after the changes are made.
