"Latest" in the Header

Hi Optuma Team,

I want mention a small issue with a forum property.

If I set the background to white, the item “Latest” in the header is not visible.

Here is a screenshot:

The same issue appears when I select “All categories” the item “Categories” in the header is not visible.

Here again a screenshot:

It seems that the issue has something to do with the blue line under the words.

As mentioned a small issue but it would be helpful if it could be solved.

Thanks,
Thomas
