I am using the default skin, in case that's relevant.
A handful of my players had just signed improved contracts, and I noticed in the pending transfers thing on the manager overview homepage thing that this had put me slightly over my wage budget. The "available wage budget" was thus displayed in red and within a pair of parentheses. I immediately sought to rectify this by going to the boardroom thing and reducing my transfer budget to zero so that my wage budget would increase. On returning to the manager overview homepage thing I noticed that the "available wage budget" in the pending transfers thing was correctly displaying the new available wage budget, but it was still red. I do not recall whether the parentheses remained in place.
After hitting the continue button, the next time I was taken to the manager overview home page thing, the available wage budget was displayed entirely correctly (colours and all).
