How to undo total column color formatting

I created a few discoveries and color formatted the total and Subtotal columns.

I added color formatting to the rest of the table but was then told that this needed to be done in the Total columns as well. When I remove the total formatting the colors are still not pulling through but when I create a new discovery it works.

I’ve done a lot of discoveries that need this and really don’t want to recreate all of them.

Can you please assist?

I'm using Version 2023.15
