edit the "invalid answer" look and feel

This is a sample from the course. We only left one slide with questions. The problem appears when non of the answers is selected. The pop up looses the format. The title changes from white to black. But it should be white. (See screenshot with incorrect color)

We discovered that what is cousing the problem is the player option to revert the text from Left to Rigth to Rigth to Left. (See screenshot with correct color)

We tried to apply the color again in the "Advanced color editing" tab after the R-L option was selected, but nothing changes. The curious thing is that the colors are correct in that options, for the title it says white, but in the published version and the preview it looks black. Also, the text is not aligned to the rigth as it should be and there are no tools to control this.
