Text box font always black

My text box font colours always end up black whatever I do. I highlight the text, Right Click and chose character font colour white but it ends up black!

I have noticed if I double click inside the box the text goes white. If I click outside it rverts to black. Print preview shows black but it prints as white!

Maybe it is the software problem. Have you tried by reinstalling the software?
Note: Use the latest version of LibreOffice which should be downloaded from LibreOffice official site.
By the way, you could attach a video recording (GIF format) of your problem which will make it convenient to the experts for suggesting proper solution.

*There are many freeware softwares are available to record screen in gif format.

But this works fine for us!
